In LibreOffice Writer, I used the common apostrophe instead of the fancy apostrophe. Because of that, LibreOffice spell checker sees that as incorrect. Is there a way to fix that? I’ve already changed my apostrophe setting so that I automatically use the straight apostrophe.
Spellcheck works correctly for me even if I uncheck auto replacement in Tools>AutoCorrect>AutoCorrect Options, Localized Options tab. In case you write multilingual, did you select the proper language in the top drop-down menu?
