Sorry, I couldn't understand what Emacs feature could be involved in
that problem.

Please show a reproducible recipe that doesn't involve Tern.  Or look
into what Tern does, and show here the code that is responsible for
incorrect handling of Cyrillic characters.

Thanks.

Tern didn't call encode-coding-string on string returned by json-encode, 
before sending it over the wire.

Fixed there.
