* New ISO 15924 script codes
-Starting with ICU 55, we do not add UScriptCode constants any more until their scripts
-are encoded in Unicode, or can be assumed to be encoded in the next Unicode version.
+Starting with ICU 55, we do not add UScriptCode constants for new scripts any more
+until they are encoded in Unicode,
+or can be assumed to be encoded in the next Unicode version.
Script enum constant names want to follow the Unicode script property value aliases,
which are assigned only when the scripts are encoded.
When we encode scripts early and guess wrong, then we have confusing enum constants
and have sometimes added aliases.
-Exception: Script codes like Latf and Aran that are not subject to separate encoding
+Variant script codes like Latf and Aran that are not subject to separate encoding
can be added at any time.
+(For example, Aran could be added as USCRIPT_ARABIC_NASTALIQ.)
-Script codes not yet in ICU: http://www.unicode.org/iso15924/codechanges.html
+We add script codes used in CLDR or in the spoof checker.
+This includes combination/alias codes like Hanb and Jamo.
+See http://unicode.org/reports/tr35/#unicode_script_subtag_validity
+and look for "alias" on http://unicode.org/iso15924/iso15924-codes.html
-Added 2014-11-15, see http://bugs.icu-project.org/trac/ticket/11561
-- Adlm 166 Adlam
-- Aran 161 Arabic (Nastaliq variant)
-- Kitl 505 Khitan large script
-- Kits 288 Khitan small script
-- Marc 332 Marchen
-- Osge 219 Osage
+We add special Z* script codes like Zsye.
-Aran can be added as USCRIPT_ARABIC_NASTALIQ at any time.
+For new script codes see http://www.unicode.org/iso15924/codechanges.html
-Adlam, Marchen, and Osage are expected to go into Unicode 9;
-we should assign Unicode script property value aliases for them
-soon after Unicode 8 is released, and add them in ICU 56.
