Great.  Exp [EMAIL PROTECTED]:space:]] solves the specific problem I raised in my last posting.  However, I'd like to go a step further,
Exp [^[:alnum:]] seems to cover a broder scope (find all nonAlphaNumeric)
as in the following
<cfif REfind('[^[:alnum:]]',str)>
  ...
</cfif>

Does it make sense?  

Thanks.
