Hi, according to our tests, the Customize RC Spline dialog accepts chinese characters, but these are not displayed correctly in the 3DS Max modifier.
Is that correct, or did you notice other issue ?
Regarding the Library browser, RailClone uses yet the old browser, which is not compatible with Unicode characters.
We have plans to replace it with the new one (the same used in latest Forest versions). That should fix this problem.
Thanks for reporting it. We'll work to fix these issues.
