When you input Chinese text using IBUS "Chinese - Intelligent Pinyin" (traditional) into a Java GUI program, it is rendered as squares as if a font is missing. This worked in Fedora 37. Upgraded to 38 this evening and discovered the squares. Reproducible: Always Steps to Reproduce: 1. Boot Fedora 38's Cinnamon spin in a VM. 2. Install `java-17-openjdk` 3. Launch any Java program that allows text input. Any hello world JSwing demo will work. JDownloader's settings has some text inputs that also show this. Actual Results: Both in a toy utility and JDownloader the Chinese shows up as squares while you can see the actual Chinese characters in libpinyin's selection. Expected Results: The Chinese shows up in the Java and libpinyin. The following dnf commands will make it render again and solve the problem. dnf install google-noto-sans-cjk-fonts.noarch --allowerasing dnf install google-noto-sans-cjk-ttc-fonts Both packages must be installed. If only the fonts but not ttc package is installed, the Chinese is rendered in Java but is now squares in the libpinyin input. Libpinyin appears to need the ttc fonts. It appears something is missing from the new google-noto-sans-cjk-vf-fonts.noarch package that supercedes the above.
