In Gmail, when I receive a reply to a message with
Subject: X, and the reply has
Subject: Re: X, it correctly recognises it as a reply and sorts the message in the same thread/conversation.
However, if the reply has a subject
Aw: X or
Sv: X, as may happen when people use non-English e-mail clients, Gmail appears to not recognise the message as part of the conversation.
Is it possible to tune or configure Gmail to make it understand non-English reply prefixes?
If so, how?
