Using prefix blogname do not clean proper name

Looks that characters doesn’t trigger any filter match, so I’m adding a new one. I’m trying to take care of the other modifications as well.

Ok,
I used this plugin for a french enviroment for the first time, so I don know if it is a version issue or an herrige/ anchestor issue.

Thanks for taking note of this. My French clients will have to wait until next update then.

Im not marking this as solved, as it is a bug/ the plugin does not provide what it is expecting to to, in this case. I might come back an paste a fix if the client really need this function, or I digg into it some other time. In other words deliver a solution to make this solved.

/ Thanks
