Character Sets ISO-10646 and ISO-10646-J-1

RFC 1815       Character Sets ISO-10646 and ISO-10646-J-1      July 1995


   Finally, this memo, by no means, promotes the use of ISO 10646 on the
   Internet.  It's use is strongly discouraged, when there are other
   charsets which can encode the same information, Families of ISO 10646
   based charsets, like ISO 2022 based charsets, only forms set of
   mutually incompatible encoding systems and, unlike ISO 2022 based
   charsets [2022INT], they can not be merged together to be the single
   world wide charset.

Description of "ISO-10646"

   ISO-10646 is profiled to be the most basic part of the family of
   encodings based on ISO 10646 and contains the following minimal
   graphic characters:

      collection number and name      positions      further restriction
      ------------------------------------------------------------------
      1 BASIC LATIN                   0020-007E
      2 LATIN-1 SUPPLEMENT            00A0-00FF

   C0 and C1 control characters may also be used as specified in the
   section 16 of ISO 10646.

   The text with "ISO-10646" encodes text in 16 bit big endian form.

   As no combining characters are included, "ISO-10646" can be used with
   applications at implementation level 1.

   Left-to-right directionality should be used.

   The encoding is implemented by Windows/NT.

   For practical communication, use of "ISO-10646" is discouraged.
   "ISO-8859-1" [RFC 1345] should be used instead.
