ONTAP 9.13

Setting the volume -language option explicitly: volume create -language utf8mb4 {…}

Inheriting the volume -language option from an SVM that has been created with or modified for the option: vserver [create|modify] -language utf8mb4 {…}``volume create {…}

You cannot modify existing volumes for utf8mb4 support; you must create a new utf8mb4-ready volume, and then migrate the data using client-based copy tools.

Beginning with ONTAP 9.8, you can use the [-language <Language code>] parameter to change the volume language from *.UTF-8 to utf8mb4. To change the language of a volume, contact Fujitsu Support.

Unicode character data is typically represented in Windows file systems applications using the 16-bit Unicode Transformation Format (UTF-16) and in NFS file systems using the 8-bit Unicode Transformation Format (UTF-8).

You can use either the volume qtree command family or ONTAP System Manager to set or modify qtree names.

qtree names can include multi-byte characters in Unicode format, such as Japanese and Chinese characters.

In 9.7 and later releases, 4-byte characters are supported in qtree names, provided that the qtree is in a volume enabled for utf8mb4.
