|
|
* Constants for ISO 15924 script codes.
|
|
*
|
|
* Many of these script codes - those from Unicode's ScriptNames.txt -
|
|
* are character property values for Unicode's Script property.
|
|
* See UAX #24 Script Names (http://www.unicode.org/reports/tr24/).
|
|
*
|
|
* Starting with ICU 3.6, constants for most ISO 15924 script codes
|
|
* are included (currently excluding private-use codes Qaaa..Qabx).
|
|
* For scripts for which there are codes in ISO 15924 but which are not
|
|
* used in the Unicode Character Database (UCD), there are no Unicode characters
|
|
* associated with those scripts.
|
|
*
|
|
* For example, there are no characters that have a UCD script code of
|
|
* Hans or Hant. All Han ideographs have the Hani script code.
|
|
* The Hans and Hant script codes are used with CLDR data.
|
|
*
|
|
* ISO 15924 script codes are included for use with CLDR and similar.
