[imp] Quote-reply to mails with special chars

[Daniel Eckl]

Hi!

Actual cvs HEAD has a problem when replying to mails with (qp encoded or
not doesn't matter) 8-bit chars in body.

When replying with quoting of the original mail, the special chars (like
german umlauts) will be replaced by question marks.

I assume the following after looking at the html code:

The pages are sent in charset utf-8.
The qp encoded special chars from the source mail are decoded correctly.
But when they are put as quote into the multiline input field, they are
not encoded in utf-8. They reside in the HTML code in cleartext and so
showing up as question marks.

I have got no clue where to catch this in the imp code...

Greets,
Daniel
