GPGMail 2.5b5

When I send signed emails to certain people, I suspect windows users, they complain that my emails look like garbage. It seems like my emails aren't being decoded and so every non ascii character looks like a bunch of numbers.
Example:

Hmm ayn=C4=B1 =C5=9Fey oldu.
Yeni subdomain:

What did you expect instead

Here's what it should look like:

Hmm aynı şey old.
Yeni subdomain:

Describe steps leading to the problem.

  1. Write an email with Turkish characters in it
  2. Sign email
  3. Send it to certain users

Here's another example:

    HI Aaron,

    when sending a test mail with

    
    Hmm aynı şey old.
    Yeni subdomain:
    

    as message body, the email arrives fine in Mail and in Thunderbird on OS X. Can you please find out what email client is being used by your windows contact. Also please ask your contact to create a screenshot of the broken mail.

    All the best,
    steve

    Hi, Steve.

    I'd like to add my investigation of this problem. In fact when I send a encrypted message (UTF-8 charset) to Outlook users (Win7 x64, Outlook 2010+Outlook Privacy Plugin v40) recipients receive garbage in a text instead of non-ascii letters. I found out Outlook Privacy Plugin requires additional text line in header of an encrypted message body - "Charset: UTF-8". For example:

    -----BEGIN PGP MESSAGE-----
    Comment: GPGTools - https://gpgtools.org
    Charset: UTF-8
    

    If I add the charset line manually the message looks correctly, if don't I see a garbage.
    Do you have ideas how to make GPGTools and OutlookPP compatible?

    Thank you for support.

    I'm informing you with pleasure that i have found solution. I opened file /Users/%user name%/.gnupg/gpg.conf. Then I changed comment line to:

    Comment GPGTools - https://gpgtools.org   Charset: UTF-8
    

    Now message header includes "Charset: UTF-8". All non-ascii messages look fine.
    Certainly Mail.app must send messages in UTF8 encoding. Thus I changes mail default charset to UTF-8 (put the command in terminal):
    defaults write com.apple.mail NSPreferredMailCharset utf-8

    That's it.

    Hi Alex,

    if the mail client doesn't decode "ayn=C4=B1 =C5=9Fey" to "aynı şey", so it's a bug in this software. Sadly not every mail client or OpenPGP plugin works as it should.
    As you can see the charset is correctly set to utf-8 in the mail. So there "should" be no reason to add "Charset: UTF-8" to the Comment.
    But if it works for you, it's an acceptable workaround.

    Regards, Mento
