MuseScore Studio does not have support for characters with language variants

Issue type

Engraving bug (incorrect score rendering)

Description with steps to reproduce

1. Create a score that contains the character 零 (or any other character that has different shapes for Chinese and Japanese)
2. Set the font of the text to a font that supports both Chinese and Japanese, like Arial Unicode MS
3. The character will always display using the Japanese form, and there is no way to change it to use the Chinese form without picking a different font

I would like to be able to select the language of the text (in Score Properties or in the Properties panel) so that the correct character form can be displayed when using multilanguage fonts. However, this option does not exist.

There are many characters that have this problem. I picked one character as an example.

Supporting files, videos and screenshots

Part of the score image from MuseScore Studio 4.5.1. All of the text is Arial Unicode MS.
The bottom part of the "零" character should look different in Chinese text.

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