It’s not just a web browser issue. For example I’m transferring data in multiple Asian languages through some network API. I always need to specify the locale of the text data in a separate data field so that some UI program at the end can display the text correctly. And even then that’s not perfect, because that’s just the system locale instead of the IME locale.
