Modern letters do not seem to be working

Example: https://polishscores.org/?id=pl-wn--sd-xvi-qu-273--001-007

prӡy should be przy, for example in the second verse of the second notes of the parts.

The problem was that ӡ and Ʒ did not have mappings to z and Z.

addFromToCombined("ſ:s ʃ:s ſ:s ν:u ί:í α:a ť:k ᴣ:z ʓ:z̨ ʒ̇:ż ʒ́:ź Ʒ̇:Ż Ʒ́:Ź ӡ:z Ʒ:Z æ:ae");
