Hi, I don’t know if this will help you…
I’m from Chile, so I write in spanish. When I upgraded to 2.8.5, I had the same problem with the accents. Música became MÂsica…
so…
I went to my wp-config file and did this:
define(‘DB_CHARSET’, ‘latin1’);
define(‘DB_COLLATE’, ”);
I don’t know if that is your problem, but since nobody answered your question, maybe you should try it.
