Can i use an iOS default Chinese font instead of including a specific one?

I'm localizing my iOS game in Chinese. I want to avoid including a Chinese TTF font, adding around 40Mo to my app weight (Chinese TTF fonts are very heavy because they contain lot's of signs).

I'm thinking of using an iOS default font like Heiti SC and Heiti TC (source: http://iosfonts.com - on iPhone since iPhone 3), and so set " Include Font Data" to false (source: https://docs.unity3d.com/Manual/class-Font.html).

Has anyone already tried this kind of approach? Does it work? ^_^
