I have a Dell XPS 15 with MikTex 2.9 installed. For some reason, and without reason, when I open a tex file within TeXworks, the fonts looks like chinese (see graphic). Oddly, it compiles fine. If I create a new file and open the original file in notepad, and paste the original text from notepad to a new file within TeXworks and then try to Typeset the file I get a "Undefined control sequence." The crazy looking file is attached. I am not having this problem on my desktop nor do I have this problem if I open this same file in TeXStudio.
Thoughts on what could be causing this?
