    copied!<p>I'm facing an encoding problem in WP7. I make a json request to an API, the response includes German umlauts but for some reason it shows up incorrectly. That's the code for making the request:</p> <pre><code>public static void makeRequest(string requestString,List&lt;String&gt; parameters,Action&lt;string&gt; handleRequestResult) { //generate a random nonce and a timestamp Random rand = new Random(); Random rand2 = new Random(); string nonce1 = rand.Next().ToString(); string nonce2 = rand2.Next().ToString(); string nonce = nonce1 + nonce2; string timestamp = GetTimestamp(); //create the parameter string in alphabetical order //string parameters = "oauth_callback=" + UrlHelper.Encode("http://www.example.com"); parameters.Add("oauth_consumer_key=" + ConsumerKey); parameters.Add("oauth_nonce=" + nonce); parameters.Add("oauth_signature_method=HMAC-SHA1"); parameters.Add("oauth_timestamp=" + timestamp); parameters.Add("oauth_version=1.0"); //sorting the list of parameters (adding '&amp;' between them) string sortedParameters = sortParams(parameters); //generate a signature base on the current requeststring and parameters and adding it to request string string signature = generateSignature("GET", requestString, sortedParameters); string url = requestString + "?" + sortedParameters + "&amp;oauth_signature=" + signature; //test the request WebClient web2 = new WebClient(); web2.Encoding = UTF8Encoding.UTF8; //string result = web.DownloadString(url); web2.DownloadStringCompleted += (sender, e) =&gt; { string result = (string)e.Result; handleRequestResult(result); //App.ViewModel.LoadData(result); }; web2.DownloadStringAsync(new Uri(url)); } </code></pre> <p>And here's an example code for loading the response to the view:</p> <pre><code>public void LoadBlogPosts(string content) { if (!AddToExistingBlogs) { this.BlogPosts.Clear(); } XDocument xml = XDocument.Parse(content); foreach (XElement element in xml.Descendants("item")) { BlogViewModel newBlog = new BlogViewModel(); newBlog.Title = element.Element("title").Value; newBlog.Description = element.Element("description").Value; newBlog.Link = element.Element("link").Value; newBlog.Category = element.Element("category").Value; //newBlog.Comments = element.Element("comments").Value; newBlog.PubDate = element.Element("pubDate").Value; XNamespace dc = "http://purl.org/dc/elements/1.1/"; XNamespace wfw = "http://wellformedweb.org/CommentAPI/"; XNamespace atom = "http://www.w3.org/2005/Atom"; XNamespace sy = "http://purl.org/rss/1.0/modules/syndication/"; XNamespace slash = "http://purl.org/rss/1.0/modules/slash/"; XNamespace contentn = "http://purl.org/rss/1.0/modules/content/"; newBlog.Dccreator = element.Element(dc + "creator").Value; newBlog.Guid = element.Element("guid").Value; newBlog.WfwCommentRss = element.Element(wfw + "commentRss").Value; newBlog.SlashComments = element.Element(slash + "comments").Value; newBlog.Content = "&lt;html&gt;&lt;body style='color: white; background-color:Black'&gt;"; newBlog.Content += element.Element(contentn + "encoded").Value; newBlog.Content += "&lt;/body&gt;&lt;/html&gt;"; // //Extract images from post: // // Size the control to fill the form with a margin var reg = new Regex("src=(?:\"|\')?(?&lt;imgSrc&gt;[^&gt;]*[^/].(?:jpg|bmp|gif|png))(?:\"|\')?"); var match = reg.Match(newBlog.Content); if (match.Success) { newBlog.FeaturedImage = match.Groups["imgSrc"].Value; } else { newBlog.FeaturedImage = @"http://karkur.com/no_image.png"; } BlogPosts.Add(newBlog); } } </code></pre> <p>That's the result that I get: <img src="https://i.stack.imgur.com/SE6UH.png" alt="enter image description here"></p> <p>Basically what I need is something to unescape unicode characters in WP7: convert this: <img src="https://i.stack.imgur.com/q4hEk.png" alt="enter image description here"></p> <p>to normal characters</p>
