I don't know that there is a canonical set of characters allowed in usernames; but the ':' character is absolutely forbidden, because it's the delimiter character in /etc/passwd. Other punctuation characters that you could use might be the period (.), the comma (,), or the percent sign (%)... These should all be valid, and they're probably the ones that will give you the least problems when using them in a shell. BTW -- what are you trying to escape with this?
