The question marks are a clash between the character set used by your website files and the character set used by your server.
This does not have to do with the <meta> character set definitions because the corruption in the characters happen deeper than the browsers rendering of the HTML - between saving the file and sending it to the browser.
In WebEdit NX 1.3.5 and above, you can override the server character set definitions. To do so:
1. log on to your admin area (like www.yourwebsite.com/webedit/admin);
2. Cick on Settings;
3. Click on the Server Settings tab;
4. change the Character Set - most people will be using UTF-8, but it depends on the server and the contents being edited.
You can safely create test files to try different Character Sets until you get the results you expect.
