NPM 12.2: Interface's Chinese description displayed in "????"

I have some H3C and Huawei network devices, which support interface's Chinese description in device's configuration.

When i added these devices into NPM 12.2, these Chinese descriptions can not display correctly, all the Chinese texts displayed in "??".

And then i tried to manually modify these interfaces' captions from database, it doesn't work!  It can only modify these interfaces' captions one by one through web ui.

In NPM 10.0, i can simply modify these interfaces' captions into Chinese text from database.

Anyone have a good solution for this problem?
