\p{Extended_Pictographic} is not supported on Hermes. How does this RegExp work in the App then? It looks like this placeholder is replaced while bundling. I've added const x = /\p{Extended_Pictographic}/gu; somewhere in App.tsx and then bundled the app with the following command:

npx react-native bundle --platform android --dev true --entry-file index.ts --bundle-output index.jsbundle --assets-dest android/app/src/main/res/

This is how I got these two regular expressions, they will be identical to the ones in React Native bundle.

Ideally, we should eliminate this patch by transpiling react-native-live-markdown-parser.js with Babel plugins that would replace placeholders in RegExp and eliminate classes (as Hermes doesn't support classes too). However, we are considering using worklets instead of having a separate hard-coded bundle and this problem will no longer be relevant then.
