This template can extract the substring " " (space) from a string. i.e. it can tell if a parameter contains the space character.
It doesn't actually recognize spaces, but will return the "then" value if the first parameter contains anything besides alphanumerical characters or any of "_;:@$!*(),/". So in particular, dashes, percent signs, umlauts or any letters outside A-Za-z will trigger the "space recognition" logic.
