Yep, just font rendering has some limitations.
the moment you need anything beyond roman/latin characters (unicode, fallback glyphs, emojis, proper-RTL). you are in a dead-zone.
This issue will worsen if you’re targeting also Android and other platforms.
If it’s a plug-in and the text area scope is very clear. you’d might be better off implementing a ‘native’ (macOS/Windows) components for the actual text handling.
