backslash
     
         "\" {ASCII} code 92.  Common names: escape (from
        C/Unix); reverse slash; slosh; backslant; backwhack.  Rare:
        bash; {ITU-T}: reverse slant; reversed virgule; {INTERCAL}:
        backslat.
     
        Backslash is used to separate components in {MS-DOS}
        {pathnames}, and to introduce special character sequence in
        {C} and {Unix} strings, e.g. "\n" for newline.
