Unicode support using the KGpg 2.5.0 editor on KDE 4.6.5 appears to be broken.

Reproducible: Always

Steps to Reproduce:
1.  Open the Kgpg editor window.
2.  Type "你好" on the first line (http://en.wiktionary.org/wiki/%E4%BD%A0%E5%A5%BD).
3.  Type "ça va" on the second line (http://en.wiktionary.org/wiki/ca_va).
4.  Encrypt with any key and save as the file 'test'.
5.  Decrypt on the command line with "gpg --decrypt test" (or in the editor).
6.  Observe the strange question marks.
Actual Results:  
??
�a va

Expected Results:  
你好
ça va

The following steps using gpg work:

1.  Create a file called 'test' with the lines: "你好" and "ça va", as above.
2.  Encrypt with "gpg --encrypt test".
3.  Specify some key.
4.  Decrypt with "gpg --decrypt test.gpg".
5.  See the text:
你好
ça va
