Jens,

Thank you for pointing these out. I provided the info I did because I 
hadn't seen anyone else reply to Kevin with detailed code 
suggestions, but rather, vague suggestions.  I stated clearly that my 
suggestion was from a Cocoa perspective on how to convert NSString to 
bytes, and were only possible starting points. Given my disclaimers, 
I expected that either he (Kevin) would handle any CF issues of which 
I was unfamiliar, or that others on the list would with greater 
knowledge would respond with helpful suggestions, as you have. Again, 
thank you for sharing your knowledge in a clear and specific way, 
which I notice you do frequently, and with accuracy.

Respectfully,
--Stuart
