BCP-47 language hint(s), used mainly to disambiguate Han-only text.

Kana and Hangul already identify Japanese and Korean, so a hint is normally unnecessary for them. In a browser, navigator.languages and navigator.language are consulted automatically after explicit hints. Server integrations should pass the document language, the signed-in user's locale, or a parsed Accept-Language preference. The first applicable ja, ko, or zh hint wins.
