In the general case where you want to wrap up weird bits of binary gibberish to control hardware, why don't you just base64 it and not have to worry about which of them are magic C0 Controls and which aren't... I'm sorry, these things are just on a different planet from respectable Unicode characters that aren't a bend-sinister by-blow of the flirtation of ASCII with Bell System 201 acoustic couplers. And you know perfectly well that the people who want these aren't trying to exchange termcaps, they're trying to wrap binary gibberish in the trappings of XML interoperability. Bah. -Tim
