Unicode characters converting with Edit mode

Permalink
Hello all,

I have a customer running a site with concrete5 which was designed by a third party. Our joint customer is trying to edit content on the site, but when they open the tinymce editor all the unicode characters are converting into "“" characters.

Any content in the database in unicode format displays properly when looking at the page as well as direct in the database with phpMyAdmin.

The problem only happens when they enter the Edit mode on the site.

The database is in utf8 and the site header shows content type as utf8...

Any ideas where to look next?

Thanks! -Cheers, Peter.
