It looks to me like this is a solution for a different problem;
that is, discarding characters outside of the specified range.
Also, do we want to map newlines, etc? Anyway, irb sez:
>> a = "abc\x0adef"
=> "abc\ndef"
>> a.gsub(/[^\x20-\x7e]/, ' ')
=> "abc def"
>> a.gsub(/[^\x00-\x7e]/, ' ')
=> "abc\ndef"
