Probably missing font. I'm not sure, if we can get the correct fonts, but I'll have a look. As I don't have any files to test: Can you provide a sample file?

There is possible solution. I found moode audio also support HDMI UI out and they have same problem. But I could add the fonts by below (they have web SSH) and I could see the characters properly.

$ sudo apt install -y fonts-unfonts-core

Here is the sample song with Korean character in metadata - I attached the screenshot of Korean string, so that you can know if it is correctly displayed or not
