Encoding issues when sharing wordpress blog at Facebook

(Some english language errors my appear.)

Folks,

When I share the posts of my WP blog at Facebook, it gets garbage characters. Like this issue here.

I’ve done everything already:

• changed wp-config lots of times;
• synchronized wp-config’s CHARSET and COLLATION with MySQL database, with UTF-8 and utf8_unicode_ci
• synchronized wp-config’s CHARSET and COLLATION with MySQL database, with UTF-8 and utf8_general_ci
• put that line $this->query(“SET NAMES UTF8”);’ in wp-db.php
• converted all my PHP files to UTF-8 without BOM.
• praying and meditation.

Nothing happend.

You can understand my problem here.

Some genius know what has to be done?

ps.: my WordPress is hosted at Dreamhost.com
