Accented words in SEO

Accent or not Accent?
Cafe or Café, that's the question.
It depends on where are you targeting.
If most of your  possible customers are in the states, we should use the non accented version, because most of us keyboards doesn't even have the accented characters. If you are tageting international customers, you should use non-accented keywords in titles anyway, but you should include accented version inthe page content.
In summary, my recommendation is to use non-accented characters in titles, descriptions and keywords, and use accents and non accent in the content in a mixed way.
