I've seen that but I had to ask - .NET just calls underlaying system 
FontDialog as I think - which in turn displays a combobox to allow font 
charset selection which is actually never used.

string macro in C++ Qt and KDE libraries and work with .po files? I 
think it's a standard way for internationalization of Open Source projects.
