Well, I myself have problems to believe that :-) This would be nasty... Are you sure?
I couldn reproduce that. I made a quick test, passing a utf-8 encoded string (5 bytes correspoding to 4 unicode chars: "niño") And my glib (same Fedora 12) seems to count bytes, as it should.
#include<stdio.h> main () { char s[] = "ni\xc3\xb1o"; printf("|%.*s|\n",5,s); }
This, compiled with gcc 4.4.3, run with my root locale (utf8) did not padded a blank. i.e. it worked as expected.
