Re: [jira] Created: (HARMONY-696) Harmony regex does not support
Character.isXXX character classes
Hello Nik,
Just a kind reminder, as you may already know, a set of new isXXXX
methods have been defined since Java 1.5 which have a int (codepoint)
parameter. This may make things tricky. ;-)
Best regards,
Richard.

Hi Nik,
I just want to emphasize other constructs also should support
supplementary characters. I'm sorry if the "DO" make you confused, you
know, I still cannot use English smoothly ;-)

OK, I see, I'll provide general support for supplementary characters,
instead of patching some special functionality like character classes,
thanks for the clue.
And if you'll update regex unit tests with test cases that would be great.
BTW, what's DO?

I agree. Nik.

Unfortunately, I can provide some test cases to demonstrate other
constructs, such as X{n}, DO support supplementary characters. But I'm
not sure if other constructs need special processing. Thanks a lot.

Richard,
We have two issues here:
[688] java.util.regex.Matcher does not support Unicode supplementary characters
[696] Harmony regex does not support Character.isXXX character classes
I would prefer, if you don't mind, to fix them separately. I know that
supplementary character support is a tricky thing and will take some
time while {javaXXXX} char. classes could be fixed relatively
quick(w/o supplementary character support).
And I have a question, am I right that supplementary character affects
mostly ranges and character classes all the other constructs will work
fine w/o special processing, what do you think.
Thank you.
Nik.
