Non-English characters may or may not be rendered for proper display depending on your local computing environment. To ensure that international characters are displayed properly in Studio:
Create a new folder called "fallback" in the directory: <ADS installation directory>jre\lib\fonts
If you are working on a Windows based system, copy the Arial Unicode MS (TrueType) file: ARIALUNI.TTF from the Windows directory C:/Windows/fonts or C:/WINNT/fonts and paste it into the new fallback directory just created.
If Studio is already running, restart it so that the new Arial Unicode fonts may be used.
