Characters are being misprinted in pdf preview and compilation

mmt27's picture

For some reason, whenever I write "ff" and I use the pdf preview, it shows up as "\"  Similarly, anytime I write either "fi" or an apostrophe, a blank space is printed instead in the preview and in the pdf compilation.  Does anyone have a solution to this?

There isn't enough

There isn't enough information in your message to guess at what is causing the problem.

What version and build number of the product are you using?  Does this happen with all documents (like ones started using the Standard LaTeX Article shell) or only certain documents?  Post a sample document that shows the problem, the .log file created when you compiled the document (save the document before compiling) and the resulting PDF file.  This information should help in tracking down the problem.
