Font changes when adding text and using polish diacritics

[szymon-zdziabek]

Hello. I use the latest Adobe Reader DC x64. When I add text to some PDF documents (using Wypełnij i podpisz - Fill and sign tool) there is I think Myriad Pro font used. However, when I add some polish letters like ą, ę, ś and so on, the font changes to Minion Pro and the document looks no consistent. I've read https://helpx.adobe.com/pl/acrobat/using/default-font-pdf-editing-add-text.html, but in my version of Reader there isn't Content Editing menu. I found some font setting under the Language menu, however there are only: default, GB18030 and HKSCS options. How can I solve it and use for example Arial font?
