Hilmar,

I read that. In looking over the documentation, there's no indication of what might happen if, as in your case, an invalid character is used.

You might want to let MS know about this through their web site. I'm not sure if Esther Fan is still doing doc review, otherwise, I'd suggest that you email her about it.

I did notice that there is one difference between the "#" and "9" characters. The former allows a space to be entered. The latter does not.
