Issues with Text and Cairo

See original GitHub issue

This is probably a bug with Cairo rather than ManimCE so this might not be something you can really fix, but there are at least a couple oddities that happen when trying to use the Text command:

Characters in the Supplemental Planes (i.e. with Unicode code points 0x10000 or more) are taken to be mod 0x10000 instead. For example, characters 0x20100 and 0x10100 both display as Ā, whose code point is 0x100.
Right-to-left text isn’t supported. For example, if Arabic text is given, every character is in its isolated form, written from left to right.

The Pango description says that it supports native font handling in all of windows, mac, and linux. But that may be too much work, and we may just want to wait until Cairo is out…
