I really like Alacritty terminal emulator for its speed, simple configuration and how accurately it shows fonts. But there is bit flaw which finally stimulated me go back to wsltty - support of Unicode.

I think on native Linux Alacritty supports Unicode characters quite well. I saw test of different terminal emulators on Youtube, e.g. this one from DistroTube¹ and Alacritty held itself quite well there. But on Windows with WSL it does not work properly.

Here is Unicode test page on Alacritty on Windows with WSL:

And this is the same test page with wsltty on the same machine:

As you can see, unfortunately on Windows 10, the wsltty has full support of Unicode, while Alacritty supports only fraction of unicode symbols. I tried to switch between different fonts, but situation is the same. So, it is not a font issue, it is really Alacritty issue on Windows.
