MuseScore.com font fallback does not work for many Chinese characters

Issue type

Engraving bug (incorrect score rendering)

Description with steps to reproduce

1. Create a score that contains any of the following characters, which are used in Chinese but not in Japanese or Korean: 热 爱 纯 馏 轻 败 对 让 说 坚 样 这 时 场 态 哟
2. Set the font to anything other than "Noto Sans SC" or "Noto Serif SC"
3. Upload it to MuseScore.com. Example score link
4. The characters will be shown as boxes, even though the image server has fonts that include these characters

While some other characters display, they are randomly from different fallback fonts (some are serif and some are sans serif), and characters like 耀 and 零 are shown wrongly because Japanese versions of the characters are shown instead of Chinese versions (#27555 has more information about that problem).

Supporting files, videos and screenshots

The score image shown on MuseScore.com. I set the font as Arial Unicode MS in MuseScore Studio, but the characters are randomly from different fonts. Many common characters, like 爱 (love) and 时 (time), are not displayed at all.

Character shapes for 零 (zero). The Japanese/Korean version is the one shown in the score image.

What is the latest version of MuseScore Studio where this issue is present?

4.5.1

Regression

No.

Operating system

All

Additional context

Since this problem affects multiple languages, I suggested to the MuseScore.com staff that they should install all of the Noto Serif fonts and/or Arial Unicode MS. However, it seems like there are some other font logic problems that could not be resolved just by installing more fonts.
