ONTAP 9

Issue

  • Creating UTF-8 named files fails if those files use surrogate_pairs like non-regular character, emoji, etc.
  • Windows:

The file name you specified is not valid or too long.  Specify a different file name

  • On fixed releases of ONTAP for bug 708253, the EMS entry wafl.dir.surrpair.filename is displayed when file operations are attempted by a client.
  • In a packet trace, the error from the create request for a file with such characters will be NT Status: STATUS_OBJECT_NAME_INVALID (0xc0000033).
  • It is not possible to use surrogate pair characters until ONTAP 9.5.
