Imported .csv is coming with errors on accents

I’m importing a csv in pt-BR and it has lots of accents. I can import , no problems there.
However, characters with accent are being displayed with a square and a question mark.
Although i’m 100% able to fix it by changing the defective letters one by one while editing blocks.
I checked the csv file and it was fine. Could it be how i exported it that caused this issue?

as a note: I accidentaly opened the .csv with libreoffice calc and in the preview was also there the error. So it might be related somuehow ? I just don’t know how.
i’m uploading the .csv ( Is just a FAQs for school project ) and a printscreen with the errors. :slight_smile: thanks in advance.
sorry for bad englishLink for the …csv file
