When text/* type files are attached, Content-Type headers don't have charset
parameter. It's not easy to determine the charset of a text file being attached
without prompting users to pick one. However, there are a couple of possibilities:

1. assume text/* file being attached is in the locale character encoding
2. assume it's in the same character encoding as the current character encoding
for the mail composition
3. prompt users to pick one

Anyway, we have to specify charset in Content-Type header

Another complication :

If it's text/html, text/css, and text/xml (with their own internal charset
specification mechanism), we may be better off not adding charset parameter to
C-T header. We have to check out the RFC about this.

Once I also had to attach an EUC-KR text file to a US-ASCII message body, and
had to edit the file "Unsent Messages" manually to add the charset parameter. I
think assumption is okay but not adequate; the user has to be able to pick one.

Possibility #3 is bug 72116.

Another possibility is bug 71551: if the text attachment is not 7-bit, give it
