Hi Andrew,

I tested VT_UTF8 on the macOs Terminal software and I can confirm that VT_UTF8 renders nicely. See the attached screenshot.

Thanks,
Nate

    If we are mentioning terminal types the default terminal type on a Mac is xterm-256color. So that is going to be the default when people run OVMF on a Mac. So it would be nice if we can add that. I can help out with anything xterm-256color related. 

    Thanks,

    Andrew Fish
