No it doesn't. It's not allowing spaces, though... Is that the problem?

It's using the case-insensitive switch. Dan Joseph wrote: Also, if you want upper case letters, make sure you add A-Z: -- The above message is encrypted with double rot13 encoding.

Hi,

That a-z0-9 is where you can do it. Just add ! or . or ? to the
end:
a-z0-9!?.
Also, if you want upper case letters, make sure you add A-Z:
A-Za-z0-9!?.
