OTB chess without language

I am English, but I live in Italy and almost all the over-the-board chess I have played has been at an Italian club; mostly with Italians, though there are a few other foreigners around.

You need very little vocabulary to conduct a chess game, but I am interested in thinking about what happens if the players don't have any common language. A handshake at the beginning is very useful to indicate that both players are ready to start. And a handshake at the end serves to confirm the game is over. "J'adoube" is recognised internationally, I think, and so is knocking one's own king over to resign.

What seems to be lacking is a way to indicate the offer or the claim of a draw. I don't think there are any standard words that are used internationally like "j'adoube". I suppose one could mark "=" on the scoresheet and then offer the scoresheet to the opponent. (I think all draw offers, accepted or not, are meant to be recorded like this.)

Is there some gesture, or else an international phrase, that I don't know about? If not, I think there should be.

Yes, crossed index fingers, is a sign of a draw.

Also, the French term "remis" is also understood to be a draw offer.

Do you mean linking the curled index fingers together like hooks, or making an X?
