If you think 7-bit issues are totally obsolete, then sorry for bothering...
UTF-7 is both stateful and fragile. Stateful it has to be, because any attemp to encode a large charset AND maintain compatibility to ASCII has to be stateful. However, it is also fragile in that there is no self-sync or seek coherence (that's the advantage of UTF-8, as we all know). Borrowing from the idea of ISO-2022-JP extended into EUC, but the other way round, I had the following "Gedankenexperiment": 00..A0 stay the same FF not used C2..FE leadbytes (1 leadbyte) A1..C1 trailbytes (2 trailbytes) allowing 61 x 33 x 33 codepoints - a little more than 65536. And now, with an ISO-2022 sequence for state, reduce to 7-bit: 42..7E leadbytes (1 leadbyte) 21..41 trailbytes (2 trailbytes) Stateful, yes... fragile, no! Any relevance, or is this just an amusing experiment to be kept among geeks privately? _________________________________________________________________ Join the world’s largest e-mail service with MSN Hotmail. http://www.hotmail.com
