Read perllocale, perlre (the section on \w and \W escapes for
word/non-word characters) and locale.

You will need the correct locales compiled on your system for every
language and input method you want to support - IIRC these can take up
quite some disk space so there is a concommitant cost associated with
handling the different languages, but I don't recall it being enormous.
To be honest the one-off cost of compiling the locales is the only real
downside of this approach that I can see.
