I am currently switching from a Mac to a Windows Pc. My work on the Mac was written with TeXShop, when I open my .tex file with TeXworks (miktex 2.9) ALL letters with accents or hats are replaced by a black diamond with an inset white question mark. Is there any way I can get the right letters back without having to individually retype them by hand?
(I had a similar problem when looking at .tex files written on a PC and tried to open them on the Mac; however in those documents the letters with accent were not all replaced by the same symbol, i.e. *" would be an é, but *# would be an à etc. In that instance I just "replaced all" in my document.)
