Applications Multilanguage - Issue with Ñ and Accents

It's been a while since I worked with an Application in Spanish.
Always English!

This time, testing that my messages properties were used properly (I was just testing that I didn't miss any message), I saw something really weird:

After thinking about what happened in Japan and reading the news, I came back to this issue.

Then, I realized I was using the wrong META TAG (Charset) meta http-equiv="Content-Type" content="texthtml; charset=UTF-8"
After updating my Charset to "ISO-8859-1", everything look as I expected, hopefully I won't have to face any issue like this one with another language (like Russian, Hindi or Japanese) because as I know all of them have a different CharSet different from English and Spanish :)
