My day job involves a fair bit of coding and I do most of the stuff in the terminal. But there is one sore spot that still bugs me to this day. All terminal emulators I've used don't have complex text layout support.

CTL is something required by Arabic and Brahmic scripts. I'm from Myanmar and Myanmar script is one of the Brahmic family of scripts. I've seen Indians also having this problem with their Devanagari script as well. I mean I don't need it too often but when I do, I have to open up a GUI text editor to edit.

I just want to know if there's something inherently fundamental in terminal emulators that makes it hard to support CTL? Is there even a terminal emulator with CTL support?
