/* Compare the memory regions S1 = [s1..s1+N1-1], S2 = [s2..s2+n2-1], that
contain character sequences, lexicographically, ignoring case.
This function's result is locale dependent. Unlike memcasecmp(), it works
correctly in multibyte locales and also handles Turkish i / dotless i.
Unlike ulc_casecmp(), it does not handle the German sharp s and the Greek
final sigma. Unlike memcoll() and ulc_casecoll(), it ignores collation
order.
Return a negative number if S1 < S2, a positive number if S1 > S2, or
0 if S1 and S2 have the same contents.
Note: This function may, in multibyte locales, return 0 for strings of
different lengths! */
