In the normal case you shouldn't care at all--just use the platform
default (i.e., gchar *).   The only time it matters, i think, is if
you are looking at individual characters.  If it's utf-8, then you
store the invidual character in a gunichar (which is 32-bit unsigned
int), by using the g_utf8_get_char api.  If it's ascii, then you store
the individual character in a guchar  by casting.

I believe, the only time you specifically need unsigned char is when
you are comparing characters (e.g., using stuff from ctype.h, or
comparing characters with inequalities)
