Apache unicode question

If anyone here can answer this, I would appreciate it. Failing that, please point me to a better place to ask - I couldn't find one, nor a FAQ which deals with this.

I am running Apache from Fedora Core 3. Some of the pages that have been created for the server use unicode characters. I don't know why they were created this way, we get lots of contributors to this site, and the person who was in charge of this died recently. But in any event, they were. The problem comes up with puctuation marks, which come up correctly in some browsers, but not in others. One of the pages that has the problem is

You should see, in some browsers, odd marks that are supposed to be quotes, apostrophes, etc.

Is there some switch I can throw so that these get interpreted "correctly", or at least differently, as they are viewed? Looking at the file under od, these "problem characters" are the only ones that have exented unicode encodings - all the others are straight ascii.

I have a feeling the page in question may have been created in Europe, while most of our pages were created in the US, if that is relevant.

Thanks for any help anyone can supply.
