Make it fatal to pass malformed UTF-8.
Due to a bug in either Perl, or in some XS-code, it's possible
for a string which is supposed to be in UTF-8 format to not be
properly encoded. If you try to find out its type (digit,
punctuation) perl will now croak.
This behaviour was deprecated in Perl 5.18.
