9. Impact on Other FTP Commands

   Along with the introduction of MLST, traditional FTP commands must be
   extended to allow for the use of more than US-ASCII [1] or EBCDIC
   character sets.  In general, the support of MLST requires support for
   arbitrary character sets wherever file names and directory names are
   allowed.  This applies equally to both arguments given to the
   following commands and to the replies from them, as appropriate.

      APPE                                RMD
      CWD                                 RNFR
      DELE                                RNTO
      MKD                                 STAT
      PWD                                 STOR
      RETR                                STOU

   The arguments to all of these commands should be processed the same
   way that MLST commands and responses are processed with respect to
   handling embedded spaces, CRs and NULs.  See section 2.2.
