Regex allowing letters,letters with accents, number, dashes, underscores and spaces.

Hi there,

I'm trying to find regex which permit to allow letter, number, dashes, underscores and spaces.

I tryied that.

^[a-zA-Z0-9,.!? ]*$

also that

^[\w\s,.]+$

and PCRE

[^\p{L}\p{P}\p{N}\p{S}\p{M}]

But nothing works to me...

Can you help me please?

Thank you and S.U.+
