Any commits I have made in the area of UTF-8 are completely accidental.
I am not the UTF-8 guy.  Both bland and jylefort have expressed interest
in this.  Perhaps one of them will comment.

I'm not sure why the malloc and copy.  Why not just use g_strdup()?

I'm hoping someone like bland chimes in here.  Touching glib in such a
way makes me nervous, but bland has had experience, especially with
Cyrillic, so maybe he can offer some additional tips or insight.
