25/**
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 *

301 * Some characters are commonly used in multiple scripts.
