HttpUtility.ParseQueryString() always encodes special characters to unicode

When using HttpUtility from System.Web, I find that everytime I call the method .ParseQueryString I am having special characters encode to their unicode equivalent represent

I am not familiar with ParseQueryString, but it appears from the documentation to convert a properly formatted query into name value pairs. From your post it appears you are trying to do the opposite: convert data pairs to a properly formatted query. Instead you may try using HttpUtility.UrlEncode

string text = "ich möchte diese Bild für andere freigeben"
var urlBuilder = new UriBuilder(url);
String query = "text=" + HttpUtility.UrlEncode(text);  
urlBuilder.Query = query;
string finalUrl = urlBuilder.ToString();
