Unicode and WordPress
Sometime back… I was trying to put unicode characters(utf-8) in the title of a blog from wp-admin > settings > general. After saving it became like ?????????.
All pages had utf-8 in their meta tags so the issue was somewhere else. A working solution was found :
1. Go to phpmyadmin and select the database of this blog
2. Select table wp_options and then click operations. In table options box change collation to utf8_unicode_ci which is the last option.
3. Also change the collation of individual columns e.g.option_value to utf8_unicode_ci
Changing the table and column collation property made the thing work right.
