Hey, I was just thinking -- I haven't been following  this thread in detail 
but
if you're doing a new layout for this board i  wonder if it would make 
sense to
use a small mcu like an atmega32u4 or  stm32 onboard in place of the cp2102
usb-to-uart adapter, this way it could  have various options for character 
set
conversion too. You could set direct  pass-thru or conversion back and 
forth to
ascii using a jumper, or even  have a more complex configuration screen 
enabled
by powering up with a  button pushed or something. Just a though. 

I've been thinking about  doing a board like this but the likelyhood i'll 
get
it done anytime soon  with all the other stuff i've been meaning to do 
makes it
seems like a poor  idea to bring it up on the mailing list.. :)
