+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.
