Garble problem with Chinese character J3O

Using the SDK to open the J3O SDK with Chinese characters will display the Chinese characters as garbled characters.
Saving the file at this point will result in garbled J3o node names.

After several attempts, if you use SDK’s GLTF to J3O function, everything works fine for Chinese characters.
If the SDK is used to edit the second time then garbled characters will appear.
So far, the SDK is one of the most versatile tools I’ve ever used
I guess that’s what caused it
How do I replace the SDK with the latest JME-Core?

SDK based on jME 3.5 & 3.4 are in the works. There are unfortunately no dates I can give you. Hopefully soon.
