Spanish accented keywords… driving me crazy!

Hi, great plugin! Thank you very much.

I have a question about a situation that is driving me crazy and i cannot find exact information on the internet:

How can i put a Spanish keyword having accents? Please let me explain better:
Almast the totality of spanish people search in Google without the “correct” accented letters so instead of “Ecológica” search for “ecologica” (no accent on the second “o”)… so your plugin suggest in every case a keyword in the “no accent” version…
BUT, if i put in the page body the CORRECT accented keyword (because my post has to be grammatically correct) the plugin will tell me i’m missing the keyword… so it seems i should put the grammatically wrong version of the keyword in my post…. but it wold be a big grammar error…. so …. my question is: Do i have to put in the Keyword the ACCENTED version even if your plugin is suggesting me that people search the un accented version? How Google will interpretate my keyword settings?

Thank you!!
Angelo
