Apparently, you did not bother read the UTF-9 "spec" too (with the funny implementation in PDP10 assembly language, quite unusual in RFCs that are not the best place to exhibit such platform-specific code). You also answered on the principle of such encoding. Had I read it prior posting, I may had added a small emoticon in my reply to Rick's message ;-) Also, there's no 7-bit system, only 7-bit protocols. For them we already have UTF-7 and MIME Base64 encoding for encapsulation in restricted ASCII environments, and the Base-37 Punycode algorithm for IDNA in the even more restricted DNS environment...
