[BUG} importing PDFs with non-ascii characters doesn't work properly.
When I try to import pdfs with diacritics in their title or anywhere in the metadata, Zotero saves it wrong and just puts the diacritics next to the letter ex. "Atualização" becomes "Atualizac¸a~o".
Can you also provide a Debug ID for reproducing this?

It's actually importing the file fine, but Zotero is extracting some basic metadata from the PDF itself (hence the "Library Catalog: Zotero"), and the encoding for that is getting messed up for some reason.
However, in future Zotero versions, we plan to recombine these accents with the letters.
