I think Leonid and I were both only thinking about non-CJK charsets
here.  The OUTGOING_MAIL_CHARSET text in lynx.cfg should probably
say that it isn't fit to transcode CJK-to-anything (as long as that
is the case).  That limitation would also be in place for the mail-body
translation approach we have discussed so far.

It is caused by the naive one-to-one  D.C.S. <-> charset  mapping that
underlies all the chartrans stuff.  Since there is no "ISO 2022-JP"
D.C.S. (which wouldn't make sense afaik), there also is not unique
'LYhndl' index for the charset "iso-2202-jp".  I don't know how to
fix this - the simple (naive) one-to-one assumption simplifies a lot
of things.

Maybe we could have an unofficial/hidden "Japanese (ISO 2022)" D.C.S.
that wouldn't show up in the 'O' list.  Maybe the recently added code
for --enable-charset-choice/--with-charsets also has something to
make that easier.
