if I compose new email and attach a file with non English characters 
(e.g.: ????.txt / ??.txt) , the attachment filename will be changed to 
???.txt

This only happen for .txt file, but no problem for .png

Even I just save it in draft, it is also ???.txt

Below is part of mail source, you can see .png is using utf-8 but .txt 
is using us-ascii, I think it is the core problem.

I can't confirm this, but I don't see anything in the changelog to 
indicate it was fixed...
