Language System in Roblox Design

[Lanrellian (Lanre)]

I have made my own system of writing and have found unicode characters for each symbol which represents different letters. Normally when you enter a unicode symbol into the chat roblox changes it into a box with a cross through it.

I’m trying to make a system where each individual letter when typed would be replaced by it’s corresponding unicode symbol, would there be any way to do this?
For example Hello would become ╬◄⧊⧊◪

Would I need to design my own chat system for this?

You can use string.byte and string.char, but that won’t solve your unsupported Unicode issue.
