    Description

      When any thai characters are being used in a QML Text object as text, the application is crashing and the following error is printed into the Javascript console : 
      "
      VM221:1 Uncaught RuntimeError: Aborted(To use dlopen, you need to use Emscripten's linking support, see https://github.com/emscripten-core/emscripten/wiki/Linking). Build with -s ASSERTIONS=1 for more info.

      "

      To reproduce the issue, just simply build and run the attached project for WebAssembly (I used Qt 6.4.1) :
