Compare s1 and s2, ignoring the case of ASCII characters and any
characters after the first n in each string.
Unlike the BSD strcasecmp() function, this only recognizes standard
ASCII letters and ignores the locale, treating all non-ASCII
characters as if they are not letters.
The same warning as in g_ascii_strcasecmp() applies: Use this
function only on strings known to be in encodings where bytes
corresponding to ASCII letters always represent themselves.
