I'm downloading data from my utf-8 db, putting it in XML tags (via PHP) and then downloading it as either CSV, HTML or XML.

Opening HTML and XML in my browser or editplus (simple text program) works fine and the french accent characters display properly.

But if I download as a CSV and open in Excel, the accent characters break.

Even if I open the HTML file (which works in the browser) in Excel, the accent characters break.

For the HTML file, I'm specifying utf-8 as so....

Content-Type: text/html; charset=UTF-8

Any ideas why MS Excel would ignore the specified charset when opening a file?
When I import the file I'm able to specify 'Unicode (UTF-8)' and that works.

Also, when downloading as CSV, do I also have to specify charset?

Content-Type: text/csv; charset=UTF-8

Thanks!
