I'm using foot terminal with archlinux, with font comic mono, the glyph is lilkely to be cut off, here is the report, looks like the issue is related to font.

The font used in the report is comic-mono-font, which is related but not this one, after search for a while, I find this active fork and try to switch to this one. this is a comparison of the font effect.

the old comic-mono (on the right) is more like to be cut off more at the top, but it's more clear with small size.
this font is also cut off but is slightly better, here is it in a larger size, which you can tell the difference:

And for unicode like this, it will be very obvious:

echo  Î Ñ

the two comic fonts all loose the top part like this:

another font lxgw-wenkai looks well:

As I have no experience with font edition, is there any option to adjust the font to make sure the font is more standard so it will not be cut-off and loose info? And is it possible to convert with a similar script to make the font more clear with a small size(like 12pt or about 14px) in terminal?

The capital letters Å, Ä and Ö render as capital A and O. Ä and Ö are widely used in Finnish, while Å would be common in Swedish and we even call it as Swedish o.

While trying to debug why this font wasn't listed as an option in Windows Terminal or conhost.exe, I eventually just forced it in the JSON file. It gives me this warning now:

The FontForge FAQ suggests it should be possible to mark the font as monospaced. This would be good for showing it in dropdown panels like in conhost.exe or Windows Terminal.

this has been bugging me for so long
