This is not correct. One big difference between Glib::ustring and 
std::ustring is the way lengths and positions in the string are handled. 
If you ask a std::ustring for its length you get the number of bytes, if 
you ask Glib::ustring you get the number of characters. Same if you 
handle with substrings and that like.
This is very important if you have to truncate strings, with 
std::ustring you always risk to split a UTF-8 character in its middle if 
you do not take special care.
