Spanish accents won't show up

Hi,

I help out a website with Spanish-language content on it and
I'm having trouble with the accents. In the Dreamweaver file on my
computer, the accents show up fine. It is on the web that they end
up as question marks. Is there anything I can do? This website has
been up for a couple years and it is only in the past 6 months that
this problem has come up. Could it be because I am now using
Dreamweaver 8? THANK YOU!Spanish accents won't show up
Oh, here is a sample page.
