Dears, I use Gate Developer 8.5, and Ontology plugin, Ontology Editor : I load my initial file "test.owl", its classes' names were written in Arabic Language, but when I try to update this file , like adding sub class and try to write its name in Arabic, I get an error: invalid class name, so, how can I enable Arabic characters in Ontology Editor interfaces.
adding sub class with English name done successfully.
I'm quite surprised that class names can use Arabic characters directly.
According to this answer:

nonstandard characters in URIs need to be encoded with the percent-encoding...
You should be able to use Arabic characters in class labels without problems. But I'm not sure about class names...
