Internationalisation of text fields

[quasicomputational]

The text fields (title and description) are monolingual and in an unspecified language. Even if multiple languages + browser selection of which one to display would be overkill, the language should be indicable to allow proper display (as matters for, e.g., CJK).

I'm not sure what advantage providing the display language would provide. Unicode allows for encoding the text direction. Notifications properly display CJK and RTL languages, and only the string is provided.

[quasicomputational]

1. If the language is known, the UA can read it aloud, offer translation, etc.

2. Han unification. The same Unicode codepoint can render quite differently between lang=zh-Hans, lang=zh-Hant and lang=ja, possibly producing unacceptable results if the language information is discarded.
