A DESCRIPTION OF THE PROBLEM :
Java applications do not render Myanmar fonts correctly.
For example, you should see one glyph ကြ combined from two characters "\u1000\u103C".
JavaFX renders it as two separate glyphs.

This is exactly the same bug of : https://bugs.java.com/bugdatabase/view_bug.do?bug_id=8223558
This time it affects JavaFX14 which is not aligned to the JDK bug fix.

There's already a quick fix to incorporate into the ScriptMapper.java class.

Sadly the committer is not a contributor. We applied the patch and it's perfect.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
I did a FXML template. Find it attached
