- Thanks. That is OK. If I have an enhanced SMTP, I can send 8-bits
- that using enhanced SMTP way and so UTF-2 is fine. If not, I can
- encode UTF-2 using BASE64 into a 7-bit-safe transmission format and
- send it over existing SMTP links while still being fully MIME
- compliant either way.

- There are several explanations. These are all pragmatic explanations,
- not technical justifications:
-
- 1) There is a fairly decent sized installed base of ISO-8859-* terminals.
- 2) Many people don't understand that the transmission encoding and
- the presentation encodings only need to be convertible and do not
- necessarily have to be identical.
- 3) ISO-10646 was not finished when MIME finished and ISO-10646 had failed to
- be passed once already and it wasn't clear how long it would take for
- ISO to finish it. Under IETF/IESG rules, an RFC can only cite existing
- works not "works in progress" such as a pending ISO standard that has
- not been approved. There was desire not to have MIME publication be
- dependent on ISO getting their act together. NB: When MIME progresses
- towards full-standard status, I fully expect ISO-10646 to be specifically
- cited and its use to be encouraged.

- ASIDE:
- I wish Microsoft had thought about this as much as you all
- at Bell Labs did. It would be better if everyone used UTF-2 (IMHO).
