In German, the rule is to have a space before the percentage sign.
Reference a: http://www.duden.de/rechtschreibung/Prozent
Beispiel: 5 Prozent oder 5 %
Reference b: http://de.wikipedia.org/wiki/Prozentzeichen
Wie bei Maßeinheiten wird zwischen die Zahl und das Prozentzeichen ein geschütztes Leerzeichen gesetzt (siehe Schreibweise von Zahlen).[7] Der Duden empfiehlt hier, einen kleineren, festen Zwischenraum zu verwenden.[8]
Even better would be to use a non breaking space but that would break a lot of views, so I changed it to a simple space here.
