Glyphs don't work on Windows Edition

[James-P-Bennett]

Steps to reproduce:

1. Download, install and launch latest version of Minecraft for Windows on PC
2. Download CustomEmojis main on GitHub
3. Extract "CustomEmojisRP" into a folder, compress those contents into a zip file and rename it into a .mcpack
4. Install the file into Minecraft by double clicking.
5. When pasting the copied special unicode into the game chat, the symbol for "0xE108" converted here doesn't display anything.

It's also worth noting that scribbling over some of the default glyphs only show their vanilla counterparts thus revealing that the pack isn't loading. Checking output log only reveals that the pack was "imported and loaded successfully"
I'm stumped. If I'm doing anything wrong please help me figure out my mistake.
