Yes, \s is a whitespace regex matching element, not a space. It matches tabs, spaces and other types of whitespace, but doesn't actually define any particular character, so you don't want to use that in the replace field. The replace function wouldn't know which whitespace character to insert even if it was allowed. I've tested a search/replace operation during convert on my system and had no trouble replacing the searched regex with a single space.
