Why does MATLAB not render correctly when Japanese locale is selected on Red Hat® Enterprise Linux® 8?

After MATLAB is installed and running with Red Hat 8.x and the locale is set to Japanese, the labels/names on the toolstrip do not render correctly.

This issue most likely occurs because Java does not recognize the text font, and is unable to render the correct format, as if the text font is missing altogether.

To resolve this issue:

1. Add "fallback" directory under (matlabroot)/sys/java/jre/glnxa64/jre/lib/fonts

2. Add a link for a Japanese font of your choice with the following commands:

cd fallback

ln -s /usr/share/fonts/google-noto-cjk/NotoSansCJK-Regular.ttc NotoSansCJK-Regular.ttc

Then "ls" command displays below:

NotoSansCJK-Regular.ttc -> /usr/share/fonts/google-noto-cjk/NotoSansCJK-Regular.ttc

3. Close and relaunch MATLAB

Please refer to the following Javadoc for additional information about fallback:
