Constants for ISO 15924 script codes, and related functions.

The current set of script code constants supports at least all scripts that are encoded in the version of Unicode which ICU currently supports. The names of the constants are usually derived from the Unicode script property value aliases. See UAX #24 Unicode Script Property (http://www.unicode.org/reports/tr24/) and http://www.unicode.org/Public/UCD/latest/ucd/PropertyValueAliases.txt .

In addition, constants for many ISO 15924 script codes are included, for use with language tags, CLDR data, and similar. Some of those codes are not used in the Unicode Character Database (UCD). For example, there are no characters that have a UCD script property value of Hans or Hant. All Han ideographs have the Hani script property value in Unicode.

Private-use codes Qaaa..Qabx are not included, except as used in the UCD or in CLDR.

Starting with ICU 55, script codes are only added when their scripts have been or will certainly be encoded in Unicode, and have been assigned Unicode script property value aliases, to ensure that their script names are stable and match the names of the constants. Script codes like Latf and Aran that are not subject to separate encoding may be added at any time.

ICU Status
Stable since ICU 2.4.
