The pieces of Unicode 4.1 that would be of any concern would be the notable changes [1]. If we were to fully support Unicode 4.1 in some classes, like Character.UnicodeBlock, there may be some cases of supporting more than the Java 5 spec (RI). This is probably fine in most cases, but I'd be curious if this had any affect on the JCK or any other JRE tests.
I haven't checked the Java 6 spec lately, but it's likely that it has moved to Unicode 4.1. More than anything, I'd just like to have some sort of consensus if a question or a bug about supporting a Unicode 4.1 value comes up. If ICU supports it then I'm even more inclined to support it. -Nathan [1] http://www.unicode.org/versions/Unicode4.1.0/#NotableChanges > -----Original Message----- > From: Tim Ellison [mailto:[EMAIL PROTECTED] > Sent: Thursday, July 06, 2006 11:44 AM > To: harmony-dev@incubator.apache.org > Subject: Re: [classlib][regex] Acknowledgement of Unicode Character > Database > > Nathan Beyer wrote: > > Shouldn't we be using Unicode 4.0.1, since Java 5 RI is 4.0-based and > 4.1 is > > large upgrade?
