What is the best way to match only letters in a regex?

Question

I would really like to use \w but it also matches underscores so I'm going with [A-Za-z] which feels unnecessarily verbose and America centric. Is there a better way to do this? Something like [\w^_] (I doubt I got that syntax right)?

Answer 1

You could use /[a-z]/i or /[[:alpha:]]/ just as well. In fact, \w includes numbers so that won't even work.
