What's a good regex to include accented characters in a simple way?

Question

Right now my regex is something like this:

[a-zA-Z0-9] but it does not include accented characters like I would want to. I would also like - \' , to be included.

Answer 1

You just put:

\p(L}\p{M}

in your expression. This in Unicode will match:

• any letter character (L) from any language
• and marks (M)(i.e, a character that is to be combined with another: accent, etc.)
