FcStrCmpIgnoreCase − compare UTF‐8 strings ignoring ASCII

#include <fontconfig.h>

int FcStrCmpIgnoreCase (const FcChar8 *s1, const FcChar8

     Returns the usual <0, 0, >0 result of comparing s1 and
s2.  This test is case‐insensitive in the ASCII range and
will operate properly with UTF8 encoded strings, although it
does not check for well formed strings.
