my name – i am getting not allowed error
my_name – i am getting success message.

code

if(!preg_match('/^[0-9a-zA-Z\xe0-\xef\x80-\xbf._-]+$/i',$nickname)) {

You need to add \s for space to your regex.

I have try this :

[0-9a-zA-Z\xe0-\xef\x80-\xbf._-]+\s*

For debugging regex may be you can use this tools.
