This function works to filter all words that contain at least one international character. All contiguous sequences of markers are replaced by a single space ascii character. This filter applies to all scripts which do not use English characters. s% [a-zA-Z]*[�-�]+[a-zA-Z]*[^a-zA-Z�-�]?Nr s �r ���r )� bytearrayr �findall�extend�isalpha)r �filtered�words�word� last_charr r r �filter_international_wordsB s z(CharSetProber.filter_international_wordsc C s� t � } d } d } x� t t | � � D]� } | | | d � } | d k rW d } n | d k ri d } | d k r( | j � r( | | k r� | r� | j | | | � � | j d � | d } q( W| s� | j | | d � � | S) a� Returns a copy of ``buf`` that retains only the sequences of English alphabet and high byte characters that are not between <> characters. Also retains English alphabet and high byte characters immediately before occurrences of >. This filter can be applied to all scripts which contain both English characters and extended ASCII characters, but is currently only used by ``Latin1Prober``.
