          - 29: International ä, å, or ñ (language-dependent)
          - 30: International ö or æ (language-dependent)
          - 31: International ß or ø (language-dependent)
          - 32: International ü
          - -1 (0xFFFF): Empty/unused position

          Unused positions are filled with -1. A name shorter than 7
          characters will have trailing -1 values.
