my $utf8here, our $utf8here, and package variable $utf8here.
The actual minimal fix is in utf8.c and from NI-S,
the rest are the tests (in fresh_perl since I couldn't get
them easily to work elsewhere) and a slight behaviour change:
previously UTF-8 identifiers had to start with an alphabetic
character. No more so, now they can start with an (Unicode)
ID_Continue character (which however is not a (Unicode) digit).
(Limiting the first character to ID_Start would be rather
restrictive, since ID_Start allows only alphabetic letters.)
TODO: use vars qw($utf8here). This I don't find to be
a showstopper.
