public RepeatedField<string> LanguageHints { get; }
List of BCP-47 language codes to use for OCR. In most cases, not
specifying it yields the best results since it enables automatic language
detection. For languages based on the Latin alphabet, setting hints is
not needed. In rare cases, when the language of the text in the
image is known, setting a hint will help get better results (although it
will be a significant hindrance if the hint is wrong).
