Twitter name verification

Question

In our registration form, we now want to ask the user to enter the name of their twitter (for example, @paul).

Can anyone tell me which characters are allowed in it?

eg. az, AZ, underline, 0-9

anything else?

I believe that these are letters, numbers and underscores and a maximum of 15 characters.

A quick search opened this post (not Twitter), covering the same topic:

The above article also contains examples of regular expressions to help you check:

Full regex – /^[a-zA-Z0-9_]{1,15}$/
Perl-compatible regex – /^\w{1,15}$/
