Re: Counting Capital Letters

Hi, I've written a short regexp which will *count* how many capital letters are in a given string (the woefully simple: '/[A-Z]/') Although it's an English language web site, I'm curious how you'd count capital letters that span beyond just the standard A-Z. For example characters such as the Latin capital letter S with Acute. I'm not interested in covering all possible character sets, but I don't want to piss-off any Europeans who may register on the site and want to use one of "their own" capital letters. Anyone approached this before?

It'd probably be a good start to use [[:upper:]] rather than [A-Z]. There's also \p{Lu} if you use utf-8 mode which matches utf-8 characters with the uppercase letter property. -robin
