Checking X_URIBL_Y_255A
Testing with 5.14.0 and the issue is not there. As we still support 5.8.6 and
this might indicate some issue, might be worth a few minutes research.

I installed 5.8.9 under perlbrew and don't see that warning. Hmmm.

A perl Unicode case-folding bug, present in at least perl-5.8.[678],
fixed in perl-5.8.9, where the utf8_heavy.pl has been substantially
rewritten.
A Carp traceback from the point where the problem occurs:

The "problem" is that the "ToFold" doesn't have an alias, so
the utf8_heavy.pl barfs at line 124:
if (my $base = ($utf8::Canonical{$canonical} ||
$utf8::Canonical{ lc $utf8::PropertyAlias{$canonical} })) {
See also casefold() in Unicode::UCD man page.
perl589delta:
Improved internal UTF-8 caching code
The code that caches calculated UTF-8 byte offsets for character
offsets for a string has been re-written. Several bugs have been
located and eliminated, and the code now makes better use of the
information it has, so should be faster. [...]
[...]
o The Unicode swatch cache inside the regexp engine is now used. (the
lookup had a key mismatch, present since the initial
implementation). [RT #42839]
A workaround for this innocent bug is to avoid case-insensitive
matching (m//i) where this occurs in t/dnsbl_subtests.t:

Bug 6983: Uninitialized value in lc in t/dnsbl_subtests.t
