I've been having compatibility issues when using MikTeX with WinEDT on a Windows 7 laptop. More particularly, when I go to open certain .tex documents that someone else has been working on with a different computer and editor, strange characters appear in the file where they shouldn't, e.g. the Â character occurring in the middle of "maximum" like this "maxiÂ-mum". And when I try to build the .tex document, it fails and gives errors such as:
! Package inputenc Error: Keyboard character used is undefined (inputenc) in inputencoding `latin1'.
Looking on this site, I found this question which seems to be about the same problem I'm having Kile document doesn't work well in WinEdt. How do I convert it? However, I tried some of the suggestions mentioned there but I couldn't get them to work. First I tried downloading TeXStudio, which was mentioned in one of the comments as being able to work with UTF-8 encoding, but I still get problems with this. Specifically, the strange characters no longer appear in the .tex file when I open it in TeXStudio, but if I build a pdf, the strange characters now appear in the .pdf file. I also tried opening the .tex files in WinEDT using the UTF-8 option, and although the strange characters don't appear in the .tex document when I do this, it still won't build and returns the same errors that I get when I don't open it using the UTF-8 option.
If anyone knows a TeX editor that is more compatible than WinEDT or has an idea of how I can fix the issues I've been having WinEDT or TeXStudio, it would be much appreciated!
