Cuba Studio server window - font issue

I installed version 6.4.3 for windows and I’m having trouble entering the parameters on CUBA Studio Server window.
It seems there is an issue with the fonts as you can see in the attached file.
Thank you,



It seems something is wrong with JVM encoding.
Is the JAVA_OPTS (or STUDIO_OPTS) environment variable set in your OS? Which value has it?

I don’t have a JAVA_OPTS defined in my environment variables. Anyway I saw in studio.bat that a default JAVA_OPTS is used.
I tried with a newer version of Java (1.8.0_131), re-installed Cuba Studio but same result.
What other settings do should I check?
