Morten, the problem isn't that libxml++ doesn't "support" UTF-8 (it uses
UTF-8 for all strings, just like libxml) the issue is that
std::string::size() returns the number of bytes, but when the string
contains UTF-8 data the number of bytes is not necessarily the same as
the number of characters. glib::ustring is UTF-8 aware and can tell you
the correct number of chars.
