Sure, I can try! I'm typing the Polish characters on my keyboard with a Polish layout, so I'm not sure the best way to look them up, but I found this website where I can just type them into the search bar: https://unicodelookup.com/
For the 3 characters mentioned above:
- Capital "Ó" = U+00D3
- Lower-case "ę" = U+0119
- Lower-case "ó" = U+00F3
If you know a better way to look up the codes, please let me know!
Thanks for the great font :-)
