Check your reading before posting?  The advice actually is

      There is an exception.  Character 45 ('"-"') is always set as
      minus (its value in Adobe ISOLatin1) even though it is hyphen in
      the other encodings.  Hyphen is available as character 173 (octal
      0255) in all the Latin encodings, Cyrillic and Greek.

So try "\255".  And please don't post twice.
