Mail encoding of text

Yup. It's an Exchange 2010 problem. And no fix for this except ask your admins to upgrade Exchange to 2013 or later 😟

Apple stupidly removed the ability to adjust incoming or outgoing encodings in Mail starting with OS X 10.9. There is nothing you can do to fix that except to use webmail or another mail app. Or you could try switching your OS language to Russian, but not sure that would help.

Check your settings in System Preferences > Language & Region... the order of the languages in this list affects which language it will attempt to use first and second, et al.

Have you tried with the system language set to English?

Could you do View > Message > Raw Source on that email and copy/paste in an email to me (tom at bluesky dot org)? I will see whether there is an error in the message causing the problem.

You sent me the raw source of this web page. I need the raw source of that particular message from the Mail app.

The person who sent the message used this encoding: charset="ks_c_5601-1987". That is some ancient stuff for Korean, not Russian. The sender should fix it.

I have same issues with text encoding after I upgraded to Yosemite. Then I solved it by pure chance :-)

Forward the e-mails that you cannot read to yourself and see what happens. It worked for me with Korean and Chinese.

I have the same issue. Upgrading to El Capitan didn't solve the problem.

Bug requests in Feedback Assistant tool: for Yosemite #523042 (28 Feb 2015), for El Capitan Public Beta #966229 (20 Jul 2015)

And it's not a problem with sender's encoding.

There are the steps to reproduce the problem:

Environment:

Language&Region

Preferred Language

- English - Primary

- Russian

Region

- Russia - Russian

List sort order

- Russian

Keyboard

Text

- Correct spelling automatically = true

- Spelling = Automatic by Language

- Use smart quotes and dashes = true

Use case scenario:

1. Mail.app is running, 1 exchange account is active (exchange 2010 server)

2. Somebody sends an email in Russian using MS Outlook 2010 or 2013 that have a certain symbol in text that can be inserted in email’s text field in Outlook like this:

2.1 insert > symbol

2.2 type «space» button

2.3 Outlook autocorrection transforms the > symbol into the symbol that looks like the UNICODE sysmbol U+27A2 (usually people do so to show the quoted text)

3. Received email in Mail.app can’t be read because of bad encoding interpretation. All text looks like:

ŽąŽāŽÝŽåŽéŽÚŽÝŽāŽãŽî ŽáŽāŽÝŽåŽéŽÚŽäŽî ŽāŽäŽÓŽÖŽä ŽßŽŅ ŽáŽāŽâŽāŽã?

instead of

Получилось получить ответ на порос?

If this email is forwarded using Mail.app to somebody with Outlook 2010/2013 on Windows, received email on other side will have the same look as at Mail.app like this:

ŽąŽāŽÝŽåŽéŽÚŽÝŽāŽãŽî ŽáŽāŽÝŽåŽéŽÚŽäŽî ŽāŽäŽÓŽÖŽä ŽßŽŅ ŽáŽāŽâŽāŽã?

And YES, somehow encoding in RAW message switches from UTF-8 (default for Mail.app) or KOI8-R (default for Outlook in Windows) to Korean charset="ks_c_5601-1987".

It seems to me it's a bug in Mail.app when communicating with Outlook as Exchange client.

When you use View > Message > Raw Source in Mail on the original incoming, does it already have the junk Korean encoding? If so, then it must be Exchange that is messing it up. Mail cannot change the raw source of an incoming message.
