There is a serious font bug in the Simplified Chinese version of StarCraft 1. I suspect the issue lies with the Noto CJK font. This font contains Simplified Chinese characters, Traditional Chinese characters, and Japanese Kanji. If the priority is not specified, it will lead to font chaos, resulting in problems such as varying sizes, font styles, and stroke weights.
Your programmers should implement something similar to this:
Noto Sans CJK SC Noto Sans CJK TC Noto Sans CJK JP
