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.

DKA More clean permalinks

Rick Radko

This plugin removes the ‘/blog’ slug from the main site permalinks of a sub-folder multisite install. The intended purpose for this plugin 
is for multilingual installations where the main site is the default language (although I’m sure there are other applications). These sites 
are of often for businesses where having the ‘/blog’ in the permalink (URL) does not make sense.
‘/blog’ is automatically removed from the main site permalinks upon plugin activation.
‘/blog’ is automatically restored in permalinks upon plugin deactivation.
