What locale settings?  UTF-8 is mostly locale-independent (as an encoding), 
the only locale specific code is in the traits class to handle collation: 
and it only sees UTF-32 code points.  The on-the-fly conversions are 
performed by iterator adapters in boost/regex/pending/unicode_iterator.hpp 
and the docs for the Unicode aware code is here:
