You can do it like this too

[\w-#]

\w match any word character [a-zA-Z0-9_]

- matches the character - literally

# matches the character # literally

Simply add any extra characters you want to allow to the character class.

[a-zA-Z0-9_#-]
           ↑

Additional note: (in case you're getting an invalid range error)

Inside of a character class the hyphen has special meaning. You can place it as the first or last character of the class. In some regex implementations, you can also place directly after a range. If you place the hyphen anywhere else you need to precede it with a backslash in order to add it to your character class.
