Create vector fonts

[FabriceAuz]

Hi
I'm using micropython on a T-Pico C3 device, equipped with a ST7789 display. I use the st7789_mpy library, which enables to draw texts using vector fonts. Some samples of vector fonts are provided, but I'd like to create new ones for my application.
How can I do that? What are the available tools on Windows?
Thanks for your help.

The vector fonts are binary encoded renditions of the 1960s-era Hershey fonts. I can't immediately see how @russhughes does it.

I'm an occasional typographer. Creating a new font, even a very simple one, takes a very long time with a difficult learning curve. Is there a particular font you have in mind?

Thanks @scruss for your answer. Actually, no specific font in mind, I just want to use the font I have on my laptop on the ST7789 display, using the Micropython library provided by @russhughes.

These vector fonts are very convenient as you can choose the size very easily:
tft.draw(font, 'No Wifi', 45, 40, blue, 1)
Here, the last argumlent is the size: if it's a little too large, I can simply change it to
tft.draw(font, 'No Wifi', 45, 40, blue, 0.9)

Scaling is very useful. The library includes code to generate bitmap fonts from Truetype fonts, but that loses the ability to scale them
