Words with letter and numbers that can contain dashes and swedish characters

Question

I would like to create a regexp which validates against all english letters + the swedish "åäö (lower and uppercase)". Also, the word can contain 1 or more "-" and can be of any length.

^[a-zA-Z\\dåäöÅÄÖ\\-*]*$

Is this correct? Can it be improved? If I recall correctly, a-zA-Z icludes more than just those letters (some characters in the ascii table between az and AZ).

Update: Here are the characters that I'm refering to:

Update 2: I also want to include digits.

Answer 1

Your regex is OK, but why are you including the asterisk ( * )?

[A-Za-z] only matches ASCII letters, it's [Az] that's problematic because there are some special characters between Z and a .

So ^[a-zA-Z\\dåäöÅÄÖ-]*$ should be OK.
