Just upgraded to 2.2 and discovered that all my blog shows question marks instead of Latvian letters. It turns out wp-settings.php file is missing 2 lines of code. After the line 264
these 2 lines should be inserted:
mysql_query("SET CHARACTER SET utf8");
mysql_query("SET NAMES utf8");
Could you please insert them in the original setup package file? MySQL 5 needs this to show proper UTF-8 encoding.
