Undo string with Chinese characters is garbled

[Aaron Ecthelion]

Hi everyone!

I am on English version of After Effects and the undo string with Chinese characters is garbled.

I wrote this sample script:

var comp = app.project.activeItem;
app.beginUndoGroup('添加空对象');
comp.layers.addNull(comp.duration);
app.endUndoGroup();

 As you can see, my undo string is Chinese. And after executing this script, I found the undo string is garbled.

I even tested other script that has Chinese version, Duik Bassel. The problem is still the same:

Tested from CC 2017 to 2021. Only version 2020 and 2021 have this issue. CC 2019 and lower work perfectly. All AE are English version.

So can I assume this is a bug in After Effects? Or did I missed some magic setting?

Can any adobe staff here telling me if this could get a fix?
