As I haven't looked at libxml++ for quite some time I'm not qualified to
comment on that part. However, I can confirm that std::string is happy
to accept UTF-8 data. 's.size()' will give you the numbers of bytes in s,
not characters, then, and strlen(s.data()) will still work, too
(though, again, returning number of bytes, not characters), since both
ASCII as well as UTF-8 are NULL-terminated.
