[TYPO3-mvc] Space to '+' converted in arguments during redirect

[Nils Blattner]

Hi there

I was just wondering, when i pass arguments (a multilevel associative 
array specifically) to another action via 
(AbstractController->)redirect(), i get the arguments back with all 
spaces converted to '+' (%2B).
The html document is utf-8 encoded with <?xml version="1.0" 
encoding="utf-8"?>
before everything else.
I will fix it temporarily by doing my own htmlentities, but would be 
cool to get to the actual root of this problem.

Thanks in advance

Nils
