Two changes for the section about user defined properties.
First is that the string returned by the IsFoo function may
contains a single Unicode point. Second, it removes the
remark
that the source string has be marked as having Unicode
characters.
This is not true. p{} and P{} *always* have Unicode
semantics:
$ perl -wE 'say "Yes 1" if "xFF" =~
/w/'
$ perl -wE 'say "Yes 2" if "xFF" =~
/p/'
Yes 2
And for user defined properties:
#!/usr/bin/perl
use strict;
use warnings;
use Test::More tests => 2;
sub IsFoo {<<"--"}
F0 FF
--
ok "xF9" =~ /p/;
ok "x79" =~ /P/;
__END__

It's important to remember not to use "&" for
the first set -- that
would be intersecting with nothing (resulting in an empty
set).
-A final note on the user-defined property tests: they will
be used
-only if the scalar has been marked as having Unicode
characters.
-Old byte-style strings will not be affected.
