A recent change in Perl 5 blead is causing HTML::Parser to experience CPANtesters failures.

See: Perl/perl5#23521 for the blead-breaks-CPAN report. The breaking commit noted that "uvuni_to_utf8() ... has been deprecated since 5.32, emitting a compiler warning if actually called (for most modern compilers)."

Sample failure report: https://www.cpantesters.org/cpan/report/0d68dfc6-6e6a-11f0-a679-b295fbe7d932

The relevant code is a single line in util.c.

$ ack uvuni_to_utf8 .
util.c
162:		    tmp = (char*)uvuni_to_utf8((U8*)buf, num);

Can you investigate? Thanks.
