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�-�]?N���� �r" )� bytearrayr# �findall�extend�isalpha)r �filtered�words�word� last_chars r �filter_international_wordsz(CharSetProber.filter_international_wordsB s� � � �;�;�� � �O� � � �� � '� '�D� �O�O�D��"��I� &� &� &� �R�S�S� �I� �$�$�&�&� !�9�w�+>�+>� � � �O�O�I� &� &� &� &��r c � � t � � }d}d}t t | � � � � D ]y}| ||dz � }|dk rd}n|dk rd}|dk rS|� � � s?||k r4|s2|� | ||� � � |� d� � |dz }�z|s |� | |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.
