BE 15 NDMP language garbled

Hi All :

I met a NDMP proble.

environmnet:

os: windows 2012 R2 cht

BE : 15 FP5 and all hotfix.

Question:

I try to backup the data on the volume of NetApp by NDMP.

and the files name which is chinese appears in backup selection is garbled.

I notise the language code on NetApp is "undifined."

even I try to adjust the regester value is 1 . following below.

the problim is still.

I read article about NetApp NDMP. they said change the language code of volume may have some effects.

Does anyone know this issue ? how to solve?
