title: Azure Blob Metadata encoding
body: <p>What is the correct way to encode the strings into the Azure Blob Metadata?</p>
  
  <p>When using Azure Storage Explorer, it seems to use a function close to C# UWPs <code>WebUtiliy.UrlEncode</code>.  But unfortunately WebUtilty.UrlEncode replaces the empty spaces with "+" signs (Storage Explorer keeps the spaces as is)</p>
  
  <p>Is there any other builtin encoding method so I can keep compatibility of my metadata between my application and the Storage Explorer?</p>
  
  <p>Thanks</p>
