We define three types of bytes:
alphabet: english alphabets [a-zA-Z]
international: international characters [€-ÿ]
marker: everything else [^a-zA-Z€-ÿ]
The input buffer can be thought to contain a series of words delimited
by markers. 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.
