Neither SCSU nor UTF-7 are TES's; they are both CES's (and are even registered as IANA charsets, to prove the point). There is of course nothing in the definition of a CES/charset (in the IETF or W3C or UTR#17 models) that requires it to be stateless, or that requires encodings of code points not to "overlap". - -- David Hopwood <[EMAIL PROTECTED]> Home page & PGP public key: http://www.users.zetnet.co.uk/hopwood/ RSA 2048-bit; fingerprint 71 8E A6 23 0E D3 4C E5 0F 69 8C D4 FA 66 15 01 Nothing in this message is intended to be legally binding.
