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€-˙]?i˙˙˙˙s€R(t bytearrayRtfindalltextendtisalpha(Rtfilteredtwordstwordt last_char((sJ/data/av2000/b2b/venv/lib/python2.7/site-packages/chardet/charsetprober.pytfilter_international_wordsBs      cCsčtƒ}t}d}x˛tt|ƒƒD]ž}|||d!}|dkrTt}n|dkrit}n|dkr(|jƒ r(||krš| rš|j|||!ƒ|jdƒn|d}q(q(W|sä|j||ƒn|S(sČ Returns a copy of ``buf`` that retains only the sequences of English alphabet and high byte characters that are not between <> characters.
