If they look like the single and double quote examples near the top right of the following link, that is how they should be: http://en.wikipedia.org/wiki/Quotation_mark Also note the following quotation copied from that link: "Depending on the typeface, opening and closing quotation marks may be identical in form (called vertical, straight, or typewriter quotation marks), or may be distinctly left-handed and right-handed (typographic or, colloquially, curly quotation marks)."
If that is not what you want, in most word processor applications you can turn it off by looking for quote marks or something similar in Autocorrect or Autocorrection.
