I've checked your movable type and while the character looks good inside MT (UTF-8 encoding), the output is filled with bad characters for each and every accent!
Your issue is that on your server HTML files are forced to have ISO-8859-1 as charset, instead of using the charset that you are declaring on the page sourc code, meta section (the modern UTF-8 standard used by movable type).
The key proving this statement is the result we get trying to validate a page with bad characters from your Web site
i.e.
http://validator.w3.org/check?uri=http%3A%...ine&group=0Character Encoding mismatch!
The character encoding specified in the HTTP header (iso-8859-1) is different from the value in the <meta> element (utf-8). I will use the value from the HTTP header (iso-8859-1) for this validation.
While there are ways to customize this at your level, my advice is to contact your hosting support and to ask them to remove that ISO-8859-1 charset imposing rule for .HTML files...
Alternatively, if you supply me access to your server FTP via PM, I should be able to fix it for you...
