Just like FcStrCopy except that it converts any leading '~' characters in
<parameter>s</parameter> to the value of the HOME environment variable.
Returns NULL if '~' is present in <parameter>s</parameter> and HOME is unset.

Returns the usual &lt;0, 0, &gt;0 result of comparing
<parameter>s1</parameter> and <parameter>s2</parameter>.  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.
