// This list was manually copied from Wikidata on 2019-05-31. It can be updated with the following command:
//
// curl "https://www.wikidata.org/w/api.php?action=query&meta=wbcontentlanguages&wbclcontext=monolingualtext&format=json&formatversion=2" | jq ".query.wbcontentlanguages[].code" | tr '\n' ','
//
// See https://stackoverflow.com/questions/46507037/how-to-get-all-allowed-languages-for-wikidata/46562061#46562061
// I don't think it is worth making every OpenRefine client perform this query at every startup, because it typically does
// not change very often.
//
// This is the list of language codes accepted for monolingualtext values. The language codes for terms are more restrictive.
// TODO: in the future, store different lists for term languages and monolingual text languages.
