Fill&Sign - Font change

[Patryk15A7]

Hi, is there any option to change font in "fill&sign" tool? When I'm filling any document, adobe reader automatically changes font when i'm using one of the polish diacritical marks (ś, ł, ó, ż etc) and it just looks terrible. I also can't see "content editing" option in preferences to change it. Thank you for your help.
