I mean that, suppose someone runs
$ export LC_CTYPE=tr_TR [or tr_TR.UTF-8]
$ dillo [or unittests]
..and setlocale(LC_CTYPE, "") pulls the tr_TR from the environment
and sets the locale, and then strcasecmp("i", "I") in Turkish is
nonzero, whereas strcasecmp("i", "İ") or strcasecmp("I", "ı") are zero.
