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.
