I'm sending this mail again because the address
        jidanni@kimo.FiXcomTHiS.tw
didn't work.  This time I use these addresses:
        jidanni@kimo.com.tw and jidanni@bigfoot.com
(I saw these addresses in his homepage.)

quoted-printable-decode-region is usually for decoding data
of quoted-printable format into the original byte sequence.
That byte sequence may be a text encoded somehow (in your
case, perhaps, big5 encoding), and thus should be decoded
again.

The docstring or quoted-printable-decode-region says as below:
----------------------------------------------------------------------
(quoted-printable-decode-region FROM TO &optional CODING-SYSTEM)

Decode quoted-printable in the region between FROM and TO, per RFC 2045.
If CODING-SYSTEM is non-nil, decode bytes into characters with that
coding-system.
----------------------------------------------------------------------

So, doing something like this will work:
    ESC : (quoted-printable-decode-region (point-min) (point-max) 'big5)

For the moment, there's no way to supply CODING-SYSTEM
interactively to that function.  Perhaps, we should modify
this function so that it respect
universal-coding-system-argument, then one can do:
    C-x RET c big5 RET M-x quoted-printable-decode-region RET
