When translating from polish (with diacritics like ęąćśźłó...) to english

Scenario 1

in Pages App > Page dialog > "Instant translation" footer actions button, then:
1) translated text have question mark in place where diacritics was

Examples:
tytuł -> title?
sprawdź -> check?
szczegóły -> details
żółć -> ?ó??
coś tam -> what? there

Scenario 2

in Pages App > "Instant translation" actionbar button, then:
1) diacritics will be replaced in the original (pl)
2) translated text have question mark in place where diacritics was

Examples:
tytuE, -> title?
sprawdЕє -> check?
szczegГіЕ‚y -> details
ЕјГіЕ‚Д‡ -> ?ó??
coЕ› tam -> what? there

I'm using DeepL translation provider and Instant translation to trigger translation
