It is nil, and default-file-name-coding-system is 'utf-8.

No, unfortunately not. Also for C-s it does not seem to make a
difference. When I enter an "ö" in *scratch*, C-u C-x = on it says:

              character: ö (246, #o366, #xf6)
      preferred charset: unicode (Unicode (ISO10646))
             code point: 0xF6
                 syntax: w 	which means: word
               category: .:Base, j:Japanese, l:Latin
               to input: type "oe" with german-postfix
            buffer code: #xC3 #xB6
              file code: #xC3 #xB6 (encoded by coding system utf-8-unix)
                display: by this font (glyph code)
          xft:-bitstream-Bitstream Vera Sans Mono-normal-normal-normal-*-20-*-*-*-m-0-iso10646-1 (#x7C)

      Character code properties: customize what to show
        name: LATIN SMALL LETTER O WITH DIAERESIS
        old-name: LATIN SMALL LETTER O DIAERESIS
        general-category: Ll (Letter, Lowercase)
        decomposition: (111 776) ('o' '̈')

      There are text properties here:
        fontified            t

This "ö" is thus also rendered with the expected font, in contrast to
the one in dired.
