Re: [Nmh-workers] RFC 2047 vs RFC 2231 encoding for MIME parameters

Hi Ken,

RFC 2047 encoding is ALSO used when you attach a filename with 8-bit
characters when you use the web interface for Gmail.  If you Google
"rfc 2047 vs rfc2231" you can get an idea of what happened (Chrome and
Thunderbird support it for decode, and Google uses that as
justification for keeping it ... and Chrome and Thunderbird don't want
to disable that support, because Gmail still uses it.  Argh).

That Chrome decodes the broken encoding isn't a reason for Gmail to
continue to produce it if Chrome decodes the correct content too?  Is
there somewhere where a Googler states that's the reason to keep
producing RFC-violating content?

We could do with a friendly Googler as an earpiece.  :-)  The ones I
know are all Xooglers now.  I wonder if Go's
https://golang.org/pkg/net/mail/#ReadMessage cares.

I'm all for balking at handling it, similar to

    mhshow: "multipart/mixed" type in message 9740 must be encoded in
    7bit, 8bit, or binary, per RFC 2045 (6.4).  One workaround is to
    manually edit the file and change the "Quoted-printable"
    Content-Transfer-Encoding to one of those.  For now, continuing...

BTW, that "continuing..." means skipping that one particular
multipart/mixed type in that message?  It half implies "dealing with it
anyway, sigh".
