I only learned about it when somebody pointed it out to me in an HN thread a couple of years ago, like the parent. The button is small and I think since I don't speak Chinese or Japanese my brain tends to skip Chinese characters as I assume that whatever they convey is not aimed at me. It's also alone on the left-hand side, with no decoration or styling showing that it's interactive.

A flag icon or simply some more explicit text would be vastly easier to understand for me, especially if it actually looked like an interactive element.

Flags are for countries not languages. I don't like the current solution too much but I'm glad it's not flags.
