Take a menu in a tourist spot, could have it go to both languages

So just keep scanning repeatedly until it gets you to the right menu?

Wouldn’t it be easier to just have the link the QR code points to show a language picker?

Or use the available language information from the device to guess the best language (and have a picker to change)

ok, so you're going to explain to people to scan it at different angles? absurd. this is like having a hyperlink go to a random destination.
