I have a problem. When the script sends a notification about spammer to StopForumSpam.com, then the user names that are written in the Cyrillic keyboard layout does not appear in the statistics. And I think that in general are not entered into the database. Although the logs on the site contains cyrillic usernames.
Here is example. As you can see after the script reports to StopForumSpam there are blank usernames written in cyrillic (win-1251).
