But ISO 10646 is not the same as Unicode: - no character properties - no definition of normalisation or Hangul standard syllables - no BiDi algorithm - no collation algorithm - no algorithms for grapheme cluster, word, or line breaking - different treatment of requirement levels and subsetting - characters added at different times - differences in UTF validity conditions (hopefully to be fixed). In most cases, Unicode is meant, not ISO 10646. That's especially true when the text is NFC-normalised before saving, which is required in some cases (HTML, XML), and probably a good idea in many other cases. - -- 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.
