Hi Xavier, I think this is to you!
Can we have some symbols "special keyboard" for the lettering as well as for the mintmarks?
I have been suffering with this one: https://en.numista.com/catalogue/pieces34127.html
I think that there are a list of symbols, which are pretty common as mint marks, just to name a few... (the list can go on):
- lilly (of Anjou)
- flower (margaretha, that is)
- star ( 4, 5 and 6)
- dot
- diamond
- crown
- a head
... just to name a few.... the list is NOT full.... I think it would be wise to add them as symbols
