Various WD items (eg Niger) have labels in language `zh-classical` (as well as many other `zh` variants). This lang tag is invalid. Use just `zh` or use a custom subtag like `zh-x-classic` (leading `x-`, and every subtag must be max 8 chars).

Various Wikidata items (eg Niger) have labels in language `zh-classical` (as well as many other `zh-*` codes). This lang tag is invalid. We should just use BCP 47 language code `lzh` for Literary Chinese / Classical Chinese.
