How to get a font with custom width for characters?

[vgibilmanno]

I'm trying to port an old application which uses GDI to draw text. It uses the LogFont struct and CreateFontIndirect + SelectObject to create a logical font which then is mapped by GDI. By using the LogFont struct you are able to set alot of different metrics for a font. I used the PickFont application to replicate what the old application is doing. Pickfont draws text by purely using GDI. See the following screenshot:

In case you want to compile the PickFont application for yourself, visit the following repo: https://github.com/recombinant/petzold-pw5e

GDI seems to support any width value I enter when using Consolas as a font. Other fonts work well too, but not every width value seems to be supported.

Now with SkiaSharp I'm able to create a Consolas font with a TextSize of 59. But how can I change the average char width to be 21 as in the example screenshot above?

I tried looking up solutions for it but the only thing I got until now is that I possibly should use HarfBuzz to solve this, but I didn't manage to get it to work. I'm not sure though if HarfBuzz can really solve my problem
