I made some progress, I follow your advice for the sizing. So now I made my curves in Rhino in a square of 1000 units. Like that
I put curves on Y negative because I made a tool to copy SVG to clipboard and it works well in FontForge.
Also 1000 units could surely better replaced by 1024 or 2048 because it is asked by the tool.
For 1000 Default Ascent =800 Descent = 200
For 1024 Default Ascent =819 Descent = 205
So I made a little tool that reuse some of my older SVG tool

Now I make a single command that takes geometries selected and copy then to clipboard.
If you use a Brep, curves are put in FontForge with the good direction
But if there is a problem of winding, it is easy to fix in FontForge.
I didn’t make kerning but made a Ligature, the 10 is an unique symbol.
The next step could be to really automate the transfert from Rhino/Grasshopper to FontForge, like seen here
There are still many errors reported by the tool but it seems usable.
