HTML5 form validation pattern alphanumeric with spaces?

Question

I have the following input tag in my html5 form:

    Company Name*
    

        

Answer 1

My solution is to cover all the range of diacritics:

([A-z0-9À-ž\s]){2,}

A-z - this is for all latin characters

0-9 - this is for all digits

À-ž - this is for all diacritics

\s - this is for spaces

{2,} - string needs to be at least 2 characters long
