In the last time vandals create many articles which seems to have exactly the
same title. Unfortunately they insert unvisible UTF8 characters into the title.
So we get many diffferent articles which titles looks like say "Karin Stoiber".
Software should refuse creating articles with a title which includes an
unvisible character - of course "blank" must be an exception.
Vandal problem occured in de-WP. My nickname is tsor, I am administrator.
