use a better default font for tastudio
Arial shows I and l as the same thing, and we have a lot of systems where we have to use both. Consolas is much better at those, tho I dunno how many people have it by default. Yet with Arial, I don't think Linux comes with it so what happens on mono?
The default WinForms font could just be different on Mono, or Mono could ship with the MS Web fonts, I haven't checked.
Apparently you can load fonts from <EmbeddedResource/>s so worst-case we could do that.
There's also System.Drawing.FontFamily.GenericSerif and GenericMonospace. Don't know how they're implemented on Mono, but hopefully it would pick something sensible?
