As a rule, it is fundamentally impossible to operate on the _characters_ of
an UTF-8 encoded string by just looping over its bytes, so such a construct
could not work, even if islower and toupper had.
You should have a look at the Glib reference manual, especially the "Unicode
Manipulation" section <URL:
http://developer.gnome.org/doc/API/2.0/glib/glib-Unicode-Manipulation.html >.
You will probably find g_utf8_strup.
