HTTP quickGetStr with arabic letters as return value

I am trying to get some values back from the Twitter Api. But for some reason I cant receive the correct arabic letters (english works perfectly). I always get e.g.: "u0623u0628u0648 u0646".

I pretty sure need to set the charset or something, but I am really stuck and dont know where to look :-/

I did try to set:

http.put_Utf8(true); vals = http.quickGetStr(getstring);

const char* vals would hold something like "حموي" but receives "u0....."
