I am new in the forum


However, when I copy from my original Word file into Latex, the apostrophe appears as a question mark. Here are my commands and a simple example. If anybody could tell me how would TexShop recognize these as apostrophe (don't tell me go one by one) re-writing them manually in TexShop cause I have more than 50 pages....)
When I compile on LatexPdf, the apostrophe like in d'information appears as a question mark..
Thanks Latex Friends
