AFAIK, ISO-2022-JP provides such noop characters (and UTF-7 provides
an alternative encoding for ASCII characters, with UTF-8, you could
use the BOM---which is, unfortunately, not without semantic effect,
but that's a Unicode design problem anyway). This way, one of the
main problems which requires mandated Quoted-Printable encoding can be
addressed by ISO-2022-JP users, even if they use a 7bit CTE.
Such encoding is possible. But I think redundant escape sequence is a
bad idea.
All in all, the problem of "From " is NOT a PGP/MIME issue, but a
Multipart/Signed issue (which covers PGP/MIME, S/MIME, MOSS). If
people want to include such a language, it should go to RFC 1847bis.
