     26  * Constants for ISO 15924 script codes.
     27  *
     28  * Many of these script codes - those from Unicode's ScriptNames.txt -
     29  * are character property values for Unicode's Script property.
     30  * See UAX #24 Script Names (http://www.unicode.org/reports/tr24/).
     31  *
     32  * Starting with ICU 3.6, constants for most ISO 15924 script codes
     33  * are included (currently excluding private-use codes Qaaa..Qabx).
     34  * For scripts for which there are codes in ISO 15924 but which are not
     35  * used in the Unicode Character Database (UCD), there are no Unicode characters
     36  * associated with those scripts.
     37  *
     38  * For example, there are no characters that have a UCD script code of
     39  * Hans or Hant. All Han ideographs have the Hani script code.
     40  * The Hans and Hant script codes are used with CLDR data.
     41  *
     42  * ISO 15924 script codes are included for use with CLDR and similar.
     43  *
