title: file upload encoding troubles with the file name. GWT
body: <p>I have a problem when I try to upload file in my gwt project (server on gae). I have FormUpload (com.google.gwt.user.client.ui.FormPanel) end FileUpload (com.google.gwt.user.client.ui.FileUpload) inside and of course server side. 
  The problem is when I try uploads image with name which contains chart like "ó". But it is weird because when I manually change "ó" on "ó" it works (delete old ó and type from my keyboard new, the image I have is from another person send by mail). </p>
  
  <p>On my formPanel I have:</p>
  
  <pre><code>setEncoding(FormPanel.ENCODING_MULTIPART);
  setMethod(FormPanel.METHOD_POST);
  </code></pre>
  
  <p>also I tray:</p>
  
  <pre><code>setEncoding(FormPanel.ENCODING_MULTIPART+"; charset=UTF-8");
  </code></pre>
  
  <p>On server I have:</p>
  
  <pre><code>Map&lt;String, List&lt;BlobKey&gt;&gt; uploads = blobstoreService.getUploads(request);
  </code></pre>
  
  <p>and uploads size is 0.</p>
  
  <p>Also I try deprecated method:</p>
  
  <pre><code>blobstoreService.getUploadedBlobs(request);
  </code></pre>
  
  <p>Also what is strange that I can upload the same image using Firefox but on Chrome, Safari and Opera I can't so maybe its browser error (bug).</p>
  
  <p>Did anyone has a similar problem like me? I am struggling with that problem and I have no idea how to fix this behavior.    </p>
