Mark, I don't want to get into a shouting match. Suffice it to
say that we feel this is important to not leave out, and I personally
am worried about the time lag between a RFC-xxxx spec and a supplement
that addresses headers.
Finally, I do not believe your statement that ISO-2022 is being used in
headers in Asia. I correspond extensively with people in Japan, and I
have not seen a single JUNET netnews or email message with anything
other than US- ASCII in headers. I believe the JUNET standards
expressly forbid use of anything other than US-ASCII in headers.
I checked with our Japanese localization people. They said that
JUNET doesn't prohibit japanese in the headers; I know for a fact
that our (Sun's) current implementation supports this feature, and
that customers are using it (since I saw the bugs when it didn't
work right...).
