languages and special chars

[eluser]rossmurphy[/eluser]
If i have pages in another language, say ES, do i have to convert the special chars to html elements?

Or do i just make sure the file is uft-8?

So for example do i have to do this...

Code:

Sólo tienes que decirles a tus amigos que, al registrarse

or can i just use it like this..
