nbsp means a nonbreaking space. most html renderer remove double spaces, for historical reasons as far as i know. thus the nbsp was introduced, and can appear anywhere in a text, most often to do basic indentation. however, filter only works on full lines, and is thus not helpful with that. you should use 'replace' for single occurrences of strings, that can't appear in normal text:
replace " " with space in theHTML
