Bug 7607

Probably a long-term enhancement bug, but it might be useful as a meta-bug for Unicode 5.0.0 issues.

Given that Unicode 5.0.0 appears to be 'published' as of July 23, 2006 (i.e. data files are finalized, but 
the book is not due to be released until 4Q 2006, and chapters not up until 1Q2007) it may be 
worthwhile to aim for moving any Unicode 5.0.0 characters from the PUA and (at the very least) start 
work on the new allocations.

I don't think there's much reason to hesitate on moving and adding characters either.  As the Unicode 
5.0.0 page (URL linked above) says:

"In order to provide an opportunity for developers to develop Unicode 5.0 as soon as possible, these 
data files have been released ahead of the publication of the text of the standard."

While character designs for the added characters are not visible in the downloadable code charts yet, 
proposal N2991 (http://std.dkuug.dk/jtc1/sc2/wg2/docs/N2991.pdf) appears to have all of the 
characters added, as well as notes as to the original proposals for the letters added.

Of note are the following characters added to the standard as of 5.0.0 that are (presumably) highest 
priority (being from the Latin, Greek, and Cyrillic scripts, as well as various Symbols, Punctuation, and 
Diacritics):
