---------------------------------------------------------------------------- ***
Unicode 6.1 update
(TODO: Copy and adjust most of the 6.0 update instructions,
except retain this following section in this new form.
So far, this just documents the new procedure for building the property names data.)
* run genpname
(builds both pnames.icu and propname_data.h)
- ~/svn.icu/tools/trunk/bld/unicode$ c/genpname/genpname -v -d ~/svn.icu/trunk/src/source/data/in
- ~/svn.icu/tools/trunk/bld/unicode$ c/genpname/genpname -v -d ~/svn.icu/trunk/src/source/common --csource
- rebuild ICU & tools
---------------------------------------------------------------------------- ***
Unicode 6.0 update
*** related ICU Trac tickets
7264 Unicode 6.0 Update
*** Unicode version numbers
- makedata.mak
- uchar.h
(configure.in & configure: have been modified to extract the version from uchar.h)
- com.ibm.icu.util.VersionInfo
*** data files & enums & parser code
* file preparation
~/svn.icu/tools/trunk/src/unicode/c/genprops/misc$ ./ucdcopy.py ~/uni60/20100720/ucd ~/uni60/processed
- This now prepares both unidata and testdata files in respective output subfolders.
* PropertyAliases.txt changes
- new Script_Extensions property defined in the new ScriptExtensions.txt file
but not listed in PropertyAliases.txt; reported to unicode.org;
-> added to tools/trunk/src/unicode/c/genpname/SyntheticPropertyAliases.txt
scx; Script_Extensions
-> uchar.h with new UProperty section
-> com.ibm.icu.lang.UProperty, parallel with uchar.h
* PropertyValueAliases.txt changes
- 12 new block names:
Alchemical_Symbols
Bamum_Supplement
Batak
Brahmi
CJK_Unified_Ideographs_Extension_D
Emoticons
Ethiopic_Extended_A
Kana_Supplement

-> add to UCharacter.UnicodeBlock
Eclipse find UBLOCK_([^ ]+) = [0-9]+, (/.+)
replace public static final UnicodeBlock \1 = new UnicodeBlock("\1", \1_ID); \2
- Joining_Group (jg) values:
Teh_Marbuta_Goal becomes the new canonical value for the old Hamza_On_Heh_Goal which becomes an alias
-> uchar.h & UCharacter.JoiningGroup
- 3 new scripts:
sc ; Batk ; Batak
sc ; Brah ; Brahmi
sc ; Mand ; Mandaic
-> remove these from SyntheticPropertyValueAliases.txt
-> add alias USCRIPT_MANDAIC to USCRIPT_MANDAEAN
-> fix expectedLong names in cucdapi.c/TestUScriptCodeAPI()
and in com.ibm.icu.dev.test.lang.TestUScript.java

- ISO 15924 name change
Mero 100 Meroitic Hieroglyphs (was Meroitic)
-> add new alias USCRIPT_MEROITIC_HIEROGLYPHS to USCRIPT_MEROITIC
- property value alias added for Cham, was already moved out of SyntheticPropertyValueAliases.txt
* UnicodeData.txt changes
- new CJK block:
2B740;<CJK Ideograph Extension D, First>;Lo;0;L;;;;;N;;;;;
2B81D;<CJK Ideograph Extension D, Last>;Lo;0;L;;;;;N;;;;;
-> add to tools/trunk/src/unicode/c/gennames/gennames.c, with new ucdVersion
* build Unicode tools using CMake+make
* run genpname/preparse.pl (on Linux)
+ cd ~/svn.icu/tools/trunk/src/unicode/c/genpname
+ make sure that data.h is writable
+ perl preparse.pl ~/svn.icu/trunk/src > out.txt
+ preparse.pl shows no errors, out.txt Info and Warning lines look ok
* rebuild Unicode tools (at least genpname) using make
- You might first need to "make install" ICU so that the tools build can pick
up the new definitions from the installed header files.
* run genpname
- ~/svn.icu/tools/trunk/bld/unicode$ c/genpname/genpname -v -d ~/svn.icu/trunk/src/source/data/in
- rebuild ICU & tools
* update source/data/unidata/norm2/nfkc_cf.txt
- follow the instructions in nfkc_cf.txt for updating it from DerivedNormalizationProps.txt
* update source/data/unidata/norm2/uts46.txt
- download http://www.unicode.org/Public/idna/6.0.0/IdnaMappingTable.txt
to ~/svn.icu/tools/trunk/src/unicode/py
- adjust idna2nrm.py to handle new disallowed_STD3_valid and disallowed_STD3_mapped values
- ~/svn.icu/tools/trunk/src/unicode/py$ ./idna2nrm.py
- ~/svn.icu/tools/trunk/src/unicode/py$ cp uts46.txt ~/svn.icu/trunk/src/source/data/unidata/norm2
* update uts46test.cpp and UTS46Test.java if there are new characters that are equivalent to
sequences with non-LDH ASCII (that is, their decompositions contain '=' or similar)
- grep IdnaMappingTable.txt or uts46.txt for "disallowed_STD3_valid" on non-ASCII characters
- Unicode 6.0: U+2260, U+226E, U+226F
* generate core properties data files
- ~/svn.icu/tools/trunk/src/unicode$ ./makeprops.sh ~/svn.icu/trunk/src ~/svn.icu/trunk/bld
- rebuild ICU & tools
- run makeuca.sh so that genuca picks up the new nfc.nrm:
~/svn.icu/tools/trunk/src/unicode$ ./makeuca.sh ~/svn.icu/trunk/src ~/svn.icu/trunk/bld
- rebuild ICU & tools
* implement new Script_Extensions property (provisional)
- parser & generator: genprops & uprops.icu
- uscript.h, uprops.h, uchar.c, uniset_props.cpp and others, plus cintltst/cucdapi.c & intltest/usettest.cpp
- UScript.java, UCharacterProperty.java, UnicodeSet.java, TestUScript.java, UnicodeSetTest.java

UBiDiProps.java, UCaseProps.java, and several others with minor changes;
UCharacterPropertyReader.java deleted and its code folded into UCharacterProperty.java
* update Java data files
- refresh just the UCD-related files, just to be safe
- see (ICU4C)/source/data/icu4j-readme.txt
- mkdir /tmp/icu4j
- ~/svn.icu/trunk/bld$ make ICU4J_ROOT=/tmp/icu4j icu4j-data-install

* refresh Java test .txt files
- copy new .txt files into ICU4J's main/tests/core/src/com/ibm/icu/dev/data/unicode
* un-hardcode normalization skippable (NF*_Inert) test data
- removes one manual step from the Unicode upgrade, and removes dependency on one of Mark's tools
* copy updated break iterator test files
- now handled by early ucdcopy.py and
copying the uni60/processed/testdata files to ~/svn.icu/trunk/src/source/test/testdata
(old instructions:
copy from (Unicode 6.0)/ucd/auxiliary/*BreakTest-6....txt
to ~/svn.icu/trunk/src/source/test/testdata)
- they are not used in ICU4J
* UCA
- get output from Mark's tools; look in

http://www.macchiato.com/unicode/utc/additional-uca-files
http://www.unicode.org/Public/UCA/6.0.0/
http://www.unicode.org/~mdavis/uca/
- update source/data/unidata/FractionalUCA.txt with FractionalUCA_SHORT.txt
- update source/data/unidata/UCARules.txt with UCA_Rules_SHORT.txt
- update Han-implicit ranges for new CJK extensions:
swapCJK() in ucol.cpp & ImplicitCEGenerator.java
- genuca: allow bytes 02 for U+FFFE, new merge-sort character;
do not add it into invuca so that tailoring primary-after an ignorable works
- genuca: permit space between [variable top] bytes
- ucol.cpp: treat noncharacters like unassigned rather than ignorable
- run makeuca.sh:
~/svn.icu/tools/trunk/src/unicode$ ./makeuca.sh ~/svn.icu/trunk/src ~/svn.icu/trunk/bld
- rebuild ICU4C
- refresh ICU4J collation data:
(subset of instructions above for properties data refresh, except copies all coll/*)
~/svn.icu/trunk/bld$ make ICU4J_ROOT=/tmp/icu4j icu4j-data-install
mkdir -p /tmp/icu4j/com/ibm/icu/impl/data/icudt45b/coll
~/svn.icu/trunk/bld/data/out/icu4j$ cp com/ibm/icu/impl/data/icudt45b/coll/* /tmp/icu4j/com/ibm/icu/impl/data/icudt45b/coll
~/svn.icu/trunk/bld/data/out/icu4j$ jar uf ~/svn.icu4j/trunk/src/main/shared/data/icudata.jar -C /tmp/icu4j com/ibm/icu/impl/data/icudt45b
- update (ICU)/source/test/testdata/CollationTest_*.txt
and (ICU4J)/main/tests/collate/src/com/ibm/icu/dev/data/CollationTest_*.txt
with output from Mark's Unicode tools
- run all tests with the *_SHORT.txt or the full files (the full ones have comments)
- note on intltest: if collate/UCAConformanceTest fails, then
utility/MultithreadTest/TestCollators will fail as well;
fix the conformance test before looking into the multi-thread test
* When refreshing all of ICU4J data from ICU4C
- ~/svn.icu/trunk/bld$ make ICU4J_ROOT=/tmp/icu4j icu4j-data-install
- cp /tmp/icu4j/main/shared/data/icudata.jar ~/svn.icu4j/trunk/src/main/shared/data
or
- ~/svn.icu/trunk/bld$ make ICU4J_ROOT=~/svn.icu4j/trunk/src icu4j-data-install
*** LayoutEngine script information
(For details see the Unicode 5.2 change log below.)
* Run ICU4J com.ibm.icu.dev.tool.layout.ScriptNameBuilder. This generates LEScripts.h, LELanguages.h,
ScriptAndLanguageTags.h and ScriptAndLanguageTags.cpp in the working directory. (It also generates
ScriptRunData.cpp, which is no longer needed.)
The generated files have a current copyright date and "@draft" statement.
* copy the above files into <icu>/source/layout, replacing the old files.
* fix mixed line endings
* review the diffs and fix incorrect @draft and missing aliases;
Unicode-derived script codes should be "born stable" like constants in uchar.h, uscript.h etc.
* manually re-add the "Indic script xyz v.2" tags in ScriptAndLanguageTags.h

* notes on changes
- PropertyAliases.txt
moved from numeric to enumerated:
ccc ; Canonical_Combining_Class
new string properties:
NFKC_CF ; NFKC_Casefold
Name_Alias; Name_Alias
new binary properties:
Cased ; Cased
CI ; Case_Ignorable
CWCF ; Changes_When_Casefolded
CWCM ; Changes_When_Casemapped
CWKCF ; Changes_When_NFKC_Casefolded
CWL ; Changes_When_Lowercased
CWT ; Changes_When_Titlecased
CWU ; Changes_When_Uppercased
new CJK Unihan properties (not supported by ICU)
- PropertyValueAliases.txt
new block names
new scripts
one script code change:
sc ; Qaai ; Inherited
->
sc ; Zinh ; Inherited ; Qaai
new Line_Break (lb) value:
lb ; CP ; Close_Parenthesis
new Joining_Group (jg) values: Farsi_Yeh, Nya
other new values:
ccc; 214; ATA ; Attached_Above
- DerivedBidiClass.txt
new default-R range: U+1E800 - U+1EFFF
- UnicodeData.txt
all of the ISO comments are gone
new CJK block end:
9FC3;<CJK Ideograph, Last> -> 9FCB;<CJK Ideograph, Last>
new CJK block:
2A700;<CJK Ideograph Extension C, First>;Lo;0;L;;;;;N;;;;;
2B734;<CJK Ideograph Extension C, Last>;Lo;0;L;;;;;N;;;;;
* genpname
- run preparse.pl
+ cd \svn\icuproj\icu\trunk\source\tools\genpname
+ make sure that data.h is writable
+ perl preparse.pl \svn\icuproj\icu\trunk > out.txt
+ preparse.pl complains with errors like the following:
Error: sc:Egyp already set to Egyptian_Hieroglyphs, cannot set to Egyp at preparse.pl line 1322, <GEN6> line 34.
This is because ICU 4.0 had scripts from ISO 15924 which are now
added to Unicode 5.2, and the Perl script shows a conflict between SyntheticPropertyValueAliases.txt
and PropertyValueAliases.txt.
-> Removed duplicate script entries from SyntheticPropertyValueAliases.txt:
Egyp, Java, Lana, Mtei, Orkh, Armi, Avst, Kthi, Phli, Prti, Samr, Tavt
+ preparse.pl complains with errors about block names missing from uchar.h; add them
* uchar.h & uscript.h & uprops.h & uprops.c & genprops
- new block & script values
+ 26 new blocks
copy new blocks from Blocks.txt
MS VC++ 2008 regular expression:
find "^{[0-9A-F]+}\.\.{[0-9A-F]+}; {[A-Z].+}$"
replace with " UBLOCK_\3 = 172, /*[\1]*/"
+ several new script values already added in ICU 4.0 for ISO 15924 coverage
(removed from SyntheticPropertyValueAliases.txt, see genpname notes above)
+ 3 new script values added for ISO 15924 and Unicode 5.2 coverage
+ 1 new script value added for ISO 15924 coverage (not in Unicode 5.2)
(added to SyntheticPropertyValueAliases.txt)
- new Joining Group (JG) values: Farsi_Yeh, Nya
- new Line_Break (lb) value:
lb ; CP ; Close_Parenthesis
* hardcoded Unihan range end/limit
- Unihan range end moves from 9FC3 to 9FCB
search for both 9FC3 (end) and 9FC4 (limit) (regex 9FC[34], case-insensitive)
+ do change gennames.c
* Compare definitions of new binary properties with what we used to use
in algorithms, to see if the definitions changed.
- Verified that definitions for Cased and Case_Ignorable are unchanged.
The gencase tool now parses the newly public Case_Ignorable values
in case the definition changes in the future.
* uchar.c & uprops.h & uprops.c & genprops
- new numeric values that didn't exist in Unicode data before:
1/7, 1/9, 1/10, 3/10, 1/16, 3/16
the ones with denominators >9 cannot be supported by uprops.icu formatVersion 5,
therefore redesign the encoding of numeric types and values for formatVersion 6;
design for simple numbers up to at least 144 ("one gross"),
large values up to at least 10^20,
and fractions with numerators -1..17 and denominators 1..16
to cover current and expected future values
(e.g., more Han numeric values, Meroitic twelfths)
* reimplement Hangul_Syllable_Type for new Jamo characters
- the old code assumed that all Jamo characters are in the 11xx block
- Unicode 5.2 fills holes there and adds new Jamo characters in
A960..A97F; Hangul Jamo Extended-A
and in
D7B0..D7FF; Hangul Jamo Extended-B
- Hangul_Syllable_Type can be trivially derived from a subset of
Grapheme_Cluster_Break values
* build Unicode data source code for hardcoding core data

*** UCA
- update FractionalUCA.txt with new canonical closure (output from Mark's Unicode tools)
- update source/data/unidata/UCARules.txt with UCA_Rules_SHORT.txt from Mark's Unicode tools
- update source/test/testdata/CollationTest_*.txt with output from Mark's Unicode tools
[ Begin obsolete instructions:
Starting with UCA 5.2, we use the CollationTest_*_SHORT.txt files not the *_STUB.txt files.
- generate the source/test/testdata/CollationTest_*_STUB.txt files via source/tools/genuca/genteststub.py

python C:\svn\icuproj\icu\trunk\source\tools\genuca\genteststub.py CollationTest_NON_IGNORABLE_SHORT.txt CollationTest_NON_IGNORABLE_STUB.txt
python C:\svn\icuproj\icu\trunk\source\tools\genuca\genteststub.py CollationTest_SHIFTED_SHORT.txt CollationTest_SHIFTED_STUB.txt
End obsolete instructions]
- run all tests with the *_SHORT.txt or the full files (the full ones have comments)
not just the *_STUB.txt files
- note on intltest: if collate/UCAConformanceTest fails, then
utility/MultithreadTest/TestCollators will fail as well;
fix the conformance test before looking into the multi-thread test
*** Implement Cased & Case_Ignorable properties
- via UProperty; call ucase.h functions ucase_getType() and ucase_getTypeOrIgnorable()
- Problem: These properties should be disjoint, but aren't
- UTC 2009nov decision: skip all Case_Ignorable regardless of whether they are Cased or not
- change ucase.icu to be able to store any combination of Cased and Case_Ignorable
*** Implement Changes_When_Xyz properties
- without stored data
*** Implement Name_Alias property
- add it as another name field in unames.icu
- make it available via u_charName() and UCharNameChoice and
- consider it in u_charFromName()
*** Break iterators
* Update break iterator rules to new UAX versions and new property values
* Update source/test/testdata/<boundary>Test.txt files from <unicode.org ucd>/ucd/auxiliary
*** new BidiTest file
- review format and data
- copy BidiTest.txt to source/test/testdata
- write test code using this data
- fix ICU code where it fails the conformance test
*** Java
- generally, find and update code corresponding to C/C++
- UCharacter.UnicodeBlock constants:
a) add an _ID integer per new block, update COUNT
b) add a class instance per new block
Visual Studio regex:
find UBLOCK_{[^ ]+} = [0-9]+, {/.+}
replace with public static final UnicodeBlock \1 = new UnicodeBlock("\1", \1_ID); \2
- CHAR_NAME_ALIAS -> UCharacter.getNameAlias() and getCharFromNameAlias()
- port test changes to Java
*** LayoutEngine script information
(For comparison, see the Unicode 5.1 update: http://bugs.icu-project.org/trac/changeset/23833)
* Run ICU4J com.ibm.icu.dev.tool.layout.ScriptNameBuilder. This generates LEScripts.h, LELanguages.h,
ScriptAndLanguageTags.h and ScriptAndLanguageTags.cpp in the working directory. (It also generates
ScriptRunData.cpp, which is no longer needed.)
The generated files have a current copyright date and "@draft" statement.
-> Eric Mader wrote in email on 20090930:
"I think the tool has been modified to update @draft to @stable for
older scripts and to add @draft for new scripts.
(I worked with an intern on this last year.)
You should check the output after you run it."
* copy the above files into <icu>/source/layout, replacing the old files.
* fix mixed line endings
* review the diffs and fix incorrect @draft and missing aliases
* manually re-add the "Indic script xyz v.2" tags in ScriptAndLanguageTags.h
Add new default entries to the indicClassTables array in <icu>/source/layout/IndicClassTables.cpp
and the complexTable array in <icu>/source/layoutex/ParagraphLayout.cpp. (This step should be automated...)
-> Eric Mader wrote in email on 20090930:
"This is just a matter of making sure that all the per-script tables have
entries for any new scripts that were added.
If any new Indic characters were added, then the class tables in
IndicClassTables.cpp should be updated to reflect this.
John Emmons should know how to do this if it's required."
* rebuild the layout and layoutex libraries.

+ cd \svn\icuproj\icu\uni51\source\tools\genpname

+ perl preparse.pl \svn\icuproj\icu\uni51 > out.txt
+ preparse.pl complains with errors like the following:
Error: sc:Cari already set to Carian, cannot set to Cari at preparse.pl line 1308, <GEN6> line 30.
This is because ICU 3.8 had scripts from ISO 15924 which are now
added to Unicode 5.1, and the script shows a conflict between SyntheticPropertyValueAliases.txt
and PropertyValueAliases.txt.
-> Removed duplicate script entries from SyntheticPropertyValueAliases.txt:
Cari, Cham, Kali, Lepc, Lyci, Lydi, Olck, Rjng, Saur, Sund, Vaii
+ PropertyValueAliases.txt now explicitly contains values for boolean properties:
N/Y, No/Yes, F/T, False/True
-> Added N/No and Y/Yes to preparse.pl function read_PropertyValueAliases.
It will use further values from the file if present.
* uchar.h & uscript.h & uprops.h & uprops.c & genprops
- new block & script values
+ 17 new blocks
+ 11 new script values already added in ICU 3.8 for ISO 15924 coverage
(removed from SyntheticPropertyValueAliases.txt)
+ 14 new script values added for ISO 15924 coverage (not in Unicode 5.1)
(added to SyntheticPropertyValueAliases.txt)
- uprops.icu (uprops.h) only provides 7 bits for script codes.
In ICU 4.0 there are USCRIPT_CODE_LIMIT=130 script codes now.
There is none above 127 yet which is the script code for an
assigned Unicode character, so ICU 4.0 uprops.icu does not store any
script code values greater than 127.
However, it does need to store the maximum script value=USCRIPT_CODE_LIMIT-1=129
in a parallel bit field, and that overflows now.
Also, future values >=128 would be incompatible anyway.
uprops.h is modified to move around several of the bit fields
in the properties vector words, and now uses 8 bits for the script code.
Two other bit fields also grow to accommodate future growth:
Block (current count: 172) grows from 8 to 9 bits,
and Word_Break grows from 4 to 5 bits.
- renamed property Simple_Case_Folding (sfc->scf)
+ nothing to be done: handled as normal alias
- new property JSN Jamo_Short_Name
+ no new API: only contributes to the Name property
- new Grapheme_Cluster_Break (GCB) value: SM=SpacingMark

- new Word_Break (WB) values:
WB ; CR ; CR
WB ; Extend ; Extend
WB ; LF ; LF

* Further changes in the 2008-02-29 update:
- Default_Ignorable_Code_Point: The new file removes Cc, Cs, noncharacters from DICP
because they should not normally be invisible.
- new Joining Group (JG) value Burushashki_Yeh_Barree was renamed to Burushaski_Yeh_Barree (one 'h' removed)
- new Grapheme_Cluster_Break (GCB) value: PP=Prepend
- new Word_Break (WB) value: NL=Newline
* hardcoded Unihan range end/limit (see Unicode 4.1 update for comparison)
- Unihan range end moves from 9FBB to 9FC3
search for both 9FBB (end) and 9FBC (limit) (regex 9FB[BC], case-insensitive)
