The previous discussion has some good advice.

The CPAN guideline saying Unicode:: is off-limits applies to CPAN, but if you think your module belongs in CORE then you should email the perl5-porters first and find out.

So the steps are:

1) look at the existing Unicode:: modules in CORE and decide if your m
+odule belongs in CORE (ask p5p if necessary)
2) if not, pick a namespace and name
3) decide how to generate the CPAN boilerplate files (I use makemaker)
+ there is a non-trivial amount of work to make a nice CPAN module
these days!
4) add some tests
5) try your distro on different machines and when you're happy request
+ a CPAN account and upload it.
6) wait for CPAN testers to score it and fix it
7) bask in the glory of being a CPAN contributor, along with the other
+ 10,000 members! :)
