25 /**
26  * Constants for ISO 15924 script codes.
27  *
28  * The current set of script code constants supports at least all scripts
29  * that are encoded in the version of Unicode which ICU currently supports.
30  * The names of the constants are usually derived from the
31  * Unicode script property value aliases.
32  * See UAX #24 Unicode Script Property (http://www.unicode.org/reports/tr24/)
33  * and http://www.unicode.org/Public/UCD/latest/ucd/PropertyValueAliases.txt .
34  *
35  * Starting with ICU 3.6, constants for most ISO 15924 script codes
36  * are included, for use with language tags, CLDR data, and similar.
37  * Some of those codes are not used in the Unicode Character Database (UCD).
38  * For example, there are no characters that have a UCD script property value of
39  * Hans or Hant. All Han ideographs have the Hani script property value in Unicode.
40  *
41  * Private-use codes Qaaa..Qabx are not included.
42  *
43  * Starting with ICU 55, script codes are only added when their scripts
44  * have been or will certainly be encoded in Unicode,
45  * and have been assigned Unicode script property value aliases,
46  * to ensure that their script names are stable and match the names of the constants.
47  * Script codes like Latf and Aran that are not subject to separate encoding
48  * may be added at any time.
