TUS seems to suggest (4.0 on page 110) that various control pictures can be used in these special circumstances. It might even be helpful for an application to use a special "character forbidden" glyph if appropriate. Earlier in this thread, I'd said I was responding to Jim Allan's original post, of course it was Jon Hanna's. It's just one of those days.

It seems unlikely that the existence of a ".com" would unravel the fabric of the universe... (In ASCII cipher, that would be "Qapla'.com", trying to send CSUR PUA UTF-8 example, having problems with e-mailers. Still.) Best regards, James Kass .
