[protege-discussion] Displaying Chinese character in Protege using XML backend

Hi Mike,

Are you using the UTF-8 character encoding in Protege? You can check 
this in the Project->Encodings menu, or on the Protege console when it 

I have just made a test with the xml backend, and added as a class name 
a character that I inserted using the "Insert Unicode Characters" from 
the Edit menu. If you save the file and reload it, it looks fine. 
However, I also saw a square for the character that you have used in 
your file. I am not sure, but maybe you need to have Chinese character 
support installed on your computer.

We have a FAQ page about character encodings in Protege that may help:
