+* 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.
+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
+can be added at any time.
+
+Script codes not yet in ICU: http://www.unicode.org/iso15924/codechanges.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
+
+Aran can be added as USCRIPT_ARABIC_NASTALIQ at any time.
+
+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.
+
+Khitan scripts will be encoded later.
+

+
+Unicode 8.0 update for ICU ??
+
+* UCA issue from 7.0
+
+- U+1DE9 COMBINING LATIN SMALL LETTER BETA
+ sorts with Greek Beta, should sort with Latin B?
+ + Ken says:
+ No, it was deliberate:
+
+ 03B2;GREEK SMALL LETTER BETA;Ll;;;;0392;;0392
+ 1D5D;MODIFIER LETTER SMALL BETA;Lm;<super> 03B2;;;;;
+ 1DE9;COMBINING LATIN SMALL LETTER BETA;Mn;<sort> 03B2;;;;;
+ 1D66;GREEK SUBSCRIPT SMALL LETTER BETA;Ll;<sub> 03B2;;;;;
+
+ Note the relationship to U+1D5D.
+
+ When the disunified *Latin* beta base letter shows up in Unicode 8.0:
+
+ U+A7B4 LATIN CAPITAL LETTER BETA
+ U+A7B5 LATIN SMALL LETTER BETA
+
+ we could re-evaluate what U+1DE9 equates to, for collation,
+ but currently there isn’t any Latin beta to serve that function
+ in Unicode 7.0.
