[classlib][luni]A difference between Unicode4.0 and Unicode4.1 affects our implementation of j.l.Character.
Hi all,
I encounter a problem when implement the method isJavaIdentifierPart(int) in
j.l.Character. The Character U+200B was redefined[1] in Unicode4.1 and
caused a testcase[2] failed.
Our implementation is compatible with Unicode 4.1 whereas RI is compatible
with 4.0. I wonder which one should we follow.
[1]
Unicode 4.0 200B;ZERO WIDTH SPACE;Zs;0;BN;;;;;N;;;;;
Unicode 4.1 200B;ZERO WIDTH SPACE;Cf;0;BN;;;;;N;;;;;
[2]
assertFalse(isJavaIdentifierPart("\u200B"));

I have raised a non-bug difference JIRA issue at
https://issues.apache.org/jira/browse/HARMONY-1488

Looks like 200B was modified/corrected from 'space separator 'to
'format'. Therefore I'd be inclined to follow the allowances in the
spec, i.e. modify the test to allow it since it is an ignorable format
character.
