Chinese UI version revit export

When can the Chinese UI version of Revit export USD data? The Rvt family use chinese name.

The USD file format is defined by Pixar. In the past it has not supported UTF-8 (Unicode characters, such as Chinese characters or other double-byte characters).
Pixar is looking at adding the level of support needed to give the type of output you are looking for.
Once Pixar has implemented that support, we intend to update our applications and connectors. I do not have a specific time-line for that work.
