tidy_bytes(string, force = false)

Replaces all ISO-8859-1 or CP1252 characters by their UTF-8 equivalent resulting in a valid UTF-8 string.

Passing true will forcibly tidy all bytes, assuming that the string's encoding is entirely CP1252 or ISO-8859-1.

# File activesupport/lib/active_support/multibyte/unicode.rb, line 44
        def tidy_bytes(string, force = false)
          return string if string.empty? || string.ascii_only?
          return recode_windows1252_chars(string) if force
          string.scrub { |bad| recode_windows1252_chars(bad) }
        end
