When creating new post (or page) the permalink is generated automatically from title. This plugin removes „leftover“ characters (such as <code>„¢¥§</code>) from created permalink. 
NB: if you edit permalink manualy the plugin does nothing – permalink will be processed with standard WordPress procedures.
