If an Accept-Language header field is present in a request and none of the available representations for the response have a language tag that is listed as acceptable, the origin server SHOULD either disregard the Accept-Language header field by treating the response as if it is not subject to content negotiation, or honor the Accept-Language header field by sending a 406 (Not Acceptable) response. However, the latter is not encouraged, as doing so can prevent users from accessing content that they might be able to use (with translation software, for example)."
