public static interface ProfileOptions.ContentLanguage
The language of the input text for the request: Arabic, English, Japanese, Korean, or Spanish. Regional variants
 are treated as their parent language; for example, `en-US` is interpreted as `en`. The effect of the
 `Content-Language` header depends on the `Content-Type` header. When `Content-Type` is `text/plain` or `text/html`,
 `Content-Language` is the only way to specify the language. When `Content-Type` is `application/json`,
 `Content-Language` overrides a language specified with the `language` parameter of a `ContentItem` object, and
 content items that specify a different language are ignored; omit this header to base the language on the
 specification of the content items. You can specify any combination of languages for `Content-Language` and
 `Accept-Language`.
