Jay Robinson has null bytes he wants to remove from Unicode strings:

As it turns out, when you have a character string in SQL Server that contains character 0x000, it really doesn’t know what to do with it most of the time, especially when you’re dealing with Unicode strings.

Jay’s got an answer which works, so check it out.  Also, I second the use of the #sqlhelp hashtag.  There’s a great community watching that hashtag.
