Unicode support in Perl on Mac

The most recent version of Mac OS X (10.6.4) still includes Perl 5.10.0, which implements Unicode 5.0. Is it likely that Perl will be updated in a minor OS release, or will we have to wait for Mac OS X 10.7 for Perl 5.12.x which implements Unicode 5.2 ? This is relevant in step 5.01 of the XML workflow (insert <reg>).

​man page:

• Mac OS X 10.6.4: Perl 5.10.0 (which implements Unicode 5.0)
• Mac OS X 10.5: Perl 5.8.8 (which implements Unicode 4.1)
• Mac OS X 10.4: Perl 5.8.6
• Mac OS X 10.3: Perl 5.8.1
• Mac OS X 10.2: Perl 5.6.0

(Does that apply to all sub-versions or only to the latest one, e.g. 10.3.0 - 10.3.9 or only 10.3.9 ?)

• Unicode 4.1: implemented in Perl 5.8.8, included in Mac OS X 10.5.8
• Unicode 5.0: implemented in Perl 5.10.0, included in Mac OS X 10.6.3, 10.6.4
• Unicode 5.1: implemented in Perl 5.8.9/5.10.1 (see ​http://perldoc.perl.org/Unicode/Normalize.html)
• Unicode 5.2: implemented in Perl 5.12.0 (see ​http://search.cpan.org/~jesse/perl-5.12.0/pod/perl5120delta.pod)
