6.8: How can I match a locale-smart version of "/[a-zA-Z]/"?

You can use the POSIX character class syntax "/[[:alpha:]]/" documented
in perlre.

No matter which locale you are in, the alphabetic characters are the
characters in \w without the digits and the underscore. As a regex, that
looks like "/[^\W\d_]/". Its complement, the non-alphabetics, is then
everything in \W along with the digits and the underscore, or
"/[\W\d_]/".

The perlfaq-workers, a group of volunteers, maintain the perlfaq. They
are not necessarily experts in every domain where Perl might show up,
so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.

If you'd like to help maintain the perlfaq, see the details in
perlfaq.pod.
