Question

I got a problem with a javascript regex.

It doesn’t stop numbers and “!” character while it should.
It works for the others special characters, and of course I have debuged it to see if it really does the test, etc… and it does. It return true even if there is numbers in my String.

This is the RegExp :

new RegExp("^[^\\- ][A-Za-z\u00C00-\u017F\\- ]+"); // \u00C00-\u017F = À-S(latin)

It is to validate a first name in a form.

The problem is weird because I have exactly the same regex on the server side in java, and it works perfectly.

Thanks for your answers 🙂

Answer 1

You probably have some typo:

\u00C00-\u017F

C00 hex would be LARGER THAN 17F hex. But \u catches four characters only, see comment below.
