This is now fixed in Trunk, also updated tests (and code somewhat) for 
Unicode v6, and added minimalist docs: 
http://svn.boost.org/svn/boost/trunk/libs/regex/doc/html/boost_regex/ref/internal_details/uni_iter.html

None of which precludes other (better?) versions appearing as libraries in 
their own right in the future.... it's just that as these have been stable 
since 2004 it seemed sensible to give them a quick make-over rather than 
roll out all new code.

HTH, John.
