hi,
I had same problem for russian language.
I’ve used Fantastico install on my bluehost WP.
The solution is quite simple:
– in phpMyAdmin (I don’t know if you have same php interface, but the way is the same) I manually changed “Collation” setting to “utf8_unicode_ci”of next fields:
1. in wp_option -> option_value
2. in wp_comments -> comment_content
3. in wp_posts -> post_content and post_title
I hope this will help you.
