I used C-c C-a mml-attach-file and filled in the description with "提案"
and instead of 100% UTF we see ascii and big5 mentioned below.

Content-Type: text/html; charset=utf-8
Content-Disposition: inline; filename=DJ1.html
Content-Transfer-Encoding: 8bit
Content-Description: =?us-ascii?Q?=3D=3Fbig5=3FB=3F0Eg=3D=3F=3D?=

Why is that a problem?  The attachment should arrive intact to the
other side, that's the only important thing, no?

The description shouldn't be mangled like that, though.  It looks like
it's been encoded twice:

Content-Description: =?us-ascii?Q?=3D=3Fbig5=3FB=3F0Eg=3D=3F=3D?=

There's a big5 base64 text in there that's then been qp-encoded and
marked as ASCII.

The Description is getting mangled!

A mangled Description will make the user look unprofessional to his superiors.

[Message part 1 (text/plain, inline)]

And, adding some text above it,

希望臨時提案：

[DJ1.html (text/html, inline)]

[Message part 3 (text/plain, inline)]

causes:

[1. text/plain]
希望臨時提案：

[2. 粀 --- text/html; DJ1.html]
    ^^WRONG CHARACTER... 提案 has become just 粀.

As seen here:

Content-Description: =?big5?B?0Eg=?=

But that's not what you said in your original complaint: there you
said the problem was that "instead of 100% UTF we see ascii and big5
mentioned below".  And that is what you replied to.

This is now fixed on the trunk.  I sent myself an attachment with the
string in question as the description, and I now get:

[1. 提案 --- image/jpeg; rms.jpg]...

So I'm closing the bug report -- if you're still seeing this, please
reopen.
