Problem displaying special characters

Question

Hi all,
This problem has been puzzling me for weeks now, I have searched the internet looking for the answer, but found nothing conclusive.
I am trying to display these characters 'í ó é á ú ó ö' on a page, but I seem to only get a strange combination of characters.
I added this '<globalization requestEncoding="ISO-8859-1" responseEncoding="ISO-8859-1"/>' to the web.config, but it's only made some chars display correctly.
Does anyone have any ideas on this one?
Thanks in advance,
