A device can normally only display characters which are included in the fonts installed on it. Some Chinese characters are not included in the fonts that come with MacOS and iOS, so you would need to add fonts to see them.
To add fonts to iOS you can use an app like AnyFont. But whether a particular app will use such added fonts is not guaranteed.
