The one single caller of _getVariantEx() is _getVariant() and this in
turn only has 3 callers, one of which is commented out (so it can be
deleted), one of which doesn't actually do anything (so it too can be
deleted) and one which can be replaced by inlining the use of
CheckedArrayByteSink.
This also allows _getVariantEx() to be renamed to _getVariant() as it's
the only such function left now.
Fix kilogram parsing: ignore 'kilogram' as a stem, we have 'gram'.
Failures in the added unit test before the fix: withSIPrefix resulted
in 'microkilogram', and kilogram's prefix was considered to be
"ONE" (i.e. 10^0).
The complicated buffer allocation code is inherited from times past but
no longer serves any purpose, it's now possible to instead simply call
the CharString copy constructor.
By always calling the dynamic memory allocation implementation directly
instead, the fixed memory buffer boundary gets pushed one step further
towards the edges.

Document the fact
uloc_getDisplay(Language|Script|Country|Variant|Keyword|KeywordValue)
would fallback with the code, case canonicalied in same cases, and
set the status to U_USING_DEFAULT_WARNING.
No change to the implementation behavior. Only complete the missing
comments and tweak line wrap, remove double spaces and add test to
validate this pre-existing behavior that I added the documents now.

Measure: initialize unit to nullptr, and don't dereference it if it is
nullptr.

In the test data from rbbitst.txt, two or more adjacent boundary markers with
no intervening test data were accepted, with no indication of a problem.
This situation occurred, as described in bug ICU-21178, with a bad import of
some test cases from CLDR. PR #1194 corrected the problem with the test data
in ICU4C. This PR adds code to flag this situation in the test data, and
also propagates the data fix to ICU4J's copy of rbbitst.txt.
Change the mapping from rule number to boundary position to use a simple array
instead of a linear search lookup map.
Look-ahead rules have a preceding context, a boundary position, and following context.
In the implementation, when the preceding context matches, the potential boundary
position is saved. Then, if the following context proves to match, the saved boundary is
returned as an actual boundary.
Look-ahead rules are numbered, and the implementation maintains a map from
rule number to the tentative saved boundary position.
In an earlier improvement to the rule builder, the rule numbering was changed to be a
contiguous sequence, from the original sparse numbering. In anticipation of
changing the mapping from number to position to use a simple array.
CharString, when asked, appends U_FILE_SEP_CHAR at the end of the string
it holds, if it won't find U_FILE_SEP_CHAR or U_FILE_ALT_SEP_CHAR there.
The problem starts if the dir variable uses
U_FILE_ALT_SEP_CHAR which is not equal to U_FILE_SEP_CHAR. Then the
resulting path could look like this
../data\
instead of this
../data/
This patch uses U_FILE_SEP_CHAR unless it detects that the dir variable
doesn't use it, and uses U_FILE_ALT_SEP_CHAR instead.
Fix a clang compiler warning and a potential undefined behavior arising
from casting an out-of-range double to an int. See the Jira ticket for a
more detailed description of the problem.
This PR is to fix the immediate problem. Longer term, the function
may be replaced entirely - see issue ICU-21147.
If udata_create won't find U_FILE_SEP_CHAR at the end of a dir variable,
then it appends it. The problem starts if the dir variable uses
U_FILE_ALT_SEP_CHAR which is not equal to U_FILE_SEP_CHAR. Then the
resulting path could look like this
../data\mappings/cns-11643-1992.ucm
instead of this
../data/mappings/cns-11643-1992.ucm
This patch uses U_FILE_SEP_CHAR unless it detects that the dir variable
doesn't use it, and uses U_FILE_ALT_SEP_CHAR instead.

For identifying text that needs to be handled by a word dictionary for Break Iteration,
change from using a bit in the character category to sorting all dictionary categories
together, and recording the boundary between the non-dictionary and dictionary ranges.
This is internal to the implementaion. It does not affect behavior.
It does increase the number of character categories that can be handled using a
compact 8 bit Trie, from 127 to 255.
The result of pointer end + 1 will not be used if end is nullptr so it
doesn't really matter that the result of this operation is undefined,
but it's therefore also unnecessary to perform the operation at all.
Changing this removes this unnecessary operation and by doing so gives
the undefined behaviour sanitizer one thing less to worry about.
- Still allows "1234" or "cldrbug:1234" format ticket IDs
- However, docs recommend "ICU-1234" or "CLDR-1234" format
in the future.
- Other ticket IDs could be used, but won't be linkified.
- Check non-lenient rules before call lenint parsing
- Remove logKnownIssue 9503 from test code
- Adjust TestAllLocales test on ICU4C
- Add lenient checks on ICU4J
