Everything is slow. Even navigating point over the Latin (Courier)
characters is slow.

Maybe your system is faster. I suggest using a CPU monitor and moving
point around in ‘unicode.txt’. In the Windows Task manager, when doing
that, I see Emacs maxing out one entire CPU thread (25%, as my CPU has
four threads).

If you could post the necessary config lines, that would be great! The
font is installed on my system.
