You can't simply change the meta tag. The file itself has to be changed concurrently from Latin-1 to UTF-8. How you do this depends on the editor, so I can't give detailed instructions. If you are on Windows, it probably involves something more complicated than changing a popup.
Currently your browser is trying to interpret Latin-1 text as UTF-8. This will not work-- especially if that Latin-1 is really Windows-Latin-1 (a superset of ISO-Latin-1). Some Latin-1 characters will simply come through as the wrong letter; others won't display at all. The angry black diamond is the "I can't deal with this" UTF-8 character, FFFD.
Oh yes and... You will also need to take a precautionary look at your uploading program-- FTP or whatever it is-- to make sure it isn't making the wrong assumptions about file encoding. For example, earlier versions of Fetch changed all my text files (for FTP purposes, "text" includes HTML) into Mac encoding. I don't remember if I changed a setting or if it simply learned to read the meta tag.
