Alexandre Linte commented on KNOX-754:
--------------------------------------

Hello [~lmccay], sorry for the delay.

When you say "from client side as well", you mean the user that requests Knox 
from a remote host, right? If this is the case, yes all my tests were done as a 
remote client and not from localhost.

I also think it's a rewrite issue on server side.

>    Affects Versions: 0.9.1
>         Environment: Apache Knox 0.9.1, Apache Hadoop 2.7.2

> Since Knox 0.9.1, Knox can't work with files which contain special characters 
> as : é, ù, ü, è, etc... This is reproducible at 100%. It was working well 
> with Knox 0.7.0 so it's a regression. 
> This happens when doing a GET or a PUT of a file of this type, and more 
> particularly at the "location" process of the request. You can find an 
> example below:
