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

A version without the exclusion rules:

^[-'a-zA-ZÀ-ÖØ-öø-ÿ]+$

Explanation

• The ^ anchor asserts that we are at the beginning of the string
• [...] allows dash, apostrophe, digits, letters, and chars in a wide accented range,
• The + matches that one or more times
• The $ anchor asserts that we are at the end of the string
