hi monks

I'm validating some mixed English and Japanese utf-8 input . It sometimes contains a-z A-Z 0-9 entered not only from the common ascii compatible unicode range, but also this unicode range xFF10 - xFF5E

http://en.wikibooks.org/wiki/Unicode/Character_reference/F000-FFFF

for example

A (unicode x0041)

vs

Ａ (unicode xFF21 http://www.decodeunicode.org/u+FF21)

I understanding that to be safe I need to interpret unicode characters I accept only as their smallest unicode representation
e.g interpret xFF21 as x0041 (as in above)

So question is, can I use some function/module of Perl to do this, or do I have to manually convert them with a mapping. All the experimenting I've done so far, it seems like I'll have to manually do it. This surprise me if I is supposed to interpret them in their smaller representation.

cheers for any feedback, sorry for my english
