def language(self):
return self.get('<STR_LIT>')<EOL>
Returns a list of canonicalized localization codes, as picked up
        from the Accept-Language header sent by the browser. By default, this
        API will return a single element that's empty; however calling
        :func:`Misc.get` directly with `lang` you can set specific headers to
        get values back as intended.

        Returns:
            List[str]

            >>> s = _syncthing()
            >>> len(s.misc.language())
            1
            >>> s.misc.language()[0]
            ''
            >>> s.misc.get('lang', headers={'Accept-Language': 'en-us'})
            ['en-us']
