Unity Support of Right to Left Languages, especially Syriac (Assyrian)

I would like to know how can the Unity IDE and Engine support the Right-to-Left languages, especially Syriac (Assyrian/Neo-Aramaic). It does somewhat support Arabic Alphabet, but doesn't even connect the words correctly, but found an extension in the Asset Store that I can use as a workaround, but it has some limitations.

My main concern here is that I have a whole list of projects that all require Syriac (Assyrian/Neo-Aramaic) support, and Unity doesn't even recognize the letter, and it changes them to "???", because it can't decode them.

PLEASE HELP US FIX THIS ISSUE. Let me know if there is any workaround to the problem.

How can I extend Unity to allow it to accept a new language? I am ready to make it if I know the approach.

Please let me know if you need any further details. But in a nutshell, if I copy a Syriac text from a word document, and paste it in Unity GuiText or anything else, Unity does NOT decode the language properly. I would like to know if there is a way to do that, or if Unity is planning to support this feature soon.

Here is an example of a sentence in Syriac: ܫܠܳܡܐ ܘ ܫܝܢܳܐ Here is how it shows: ???? (or blocks or empty spaces)

THANK YOU.
