/**
* Constants for ISO 15924 script codes.
*
* 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.
*
* @stable ICU 2.2
