[Dev] CPIA Layer having issues handling unicode strings

[Brian Kirsch]

Hello Folks,
As a prelude to the forth coming "Internationalizing The Chandler  
Architecture" proposal I will be sending out for review later this week  
I
have gone ahead and added internationalization / localization support  
to the Email Service Layer. In addition to properly parsing and storing
attachments the Service layer will convert all headers, bodies, and  
text attachments to Unicode with the proper character set encoding as  
specified in
RFC's 2046, 2047, and 2231. I have added two additional menu items  
under "Test". The first "Mime Torture Tests" loads in to Chandler 76  
real world complex / broken
mime message examples donated by Anthony Baxter. The second "i18n Mail  
Tests" loads mime message examples in to Chandler that contain a  
variety of
Charsets and Languages.

I have not checked in this code however, because the CPIA layer is  
currently casting many objects to ASCII strings which causes runtime  
UnicodeDecodeError's.
Can someone in the CPIA GUI team take on the responsibility of going  
through the UI code and accounting for Unicode strings?

Here is stack trace of some of the errors I am encountering:
