Allow customizing font fallback

[eugenesv]

I've added a symbol missing from the Segoe UI font to the title, and it's displayed as a box. There is a font on my system that has that symbol, and if I set it in Everything config, the symbols is displayed, but I don't want to change the font (also, the titlebar has no option to change fonts)

I've tried to use both solutions found online to change font fallback (well, alternatives, as far as I understood, you can't control font fallback directly on Windows) by changing with reference to the font file, but it didn't work

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontLink\SystemLink
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes

Is it possible to instead use app APIs to add that manual control for font substitution since the OS is so bad at this?
Thanks!

This is beyond the scope of Everything.
I don't want Everything to manage font fallback.
This should be done by the OS.

Thanks for the suggestion.

Well, yes,OS should do that, but do you maybe know how to do that in Windows 11? Besides the two registry places, I've only found API descriptions for apps to use, but you don't want to use those
