[boost] Strings with character sets

Dear All, After a rather longer delay than I had planned, I have some proof-of-concept code for strings tagged with character sets. You might like to first look at the example usage, here: http://svn.chezphil.org/libpbe/trunk/examples/charsets.cc Note that this file is written using UTF8, but the web server seems to be declaring it to be latin1.... The actual implementation is here: http://svn.chezphil.org/libpbe/trunk/include/charset.hh This is far from complete, but it does have some useful functionality; mainly I have been using it to work out what is possible. Your comments would be very much appreciated. Regards, Phil.
