Cannot display U+xxxxx utf-32 symbols

**Describe the bug**
I want to display all Chinese text as well.
I found out that normal Chinese text display well.
But some hard text that encoded with 4 bytes can not get a good display and overlayed by other word.
e.g.
https://www.compart.com/en/unicode/U+24256
U+24256 "𤉖" display 'PV' in PDF.

**To Reproduce**
Steps to reproduce the behavior including code snippet (if applies):

1. register font with:
https://fonts.google.com/specimen/Cactus+Classical+Serif

which support the text '𤉖'
https://fonts.google.com/specimen/Chocolate+Classical+Sans?preview.text=%F0%A4%89%96

2. show pdf with text '𤉖'

_You can make use of [react-pdf REPL](https://react-pdf.org/repl) to share the snippet_

**Expected behavior**
I should see '𤉖' display correct in the PDF.
