title: NSURL with Curly Braces
body: <p>NSURL does not support the use of curly braces (i.e. {}) in URLs.  My application needs to talk to a server that requires the use of curly braces in the URL.  I'm considering using bridges to write the networking code in Python or C++, or even rewriting the C code for NSURL to make it accept curly braces.  Percent escapes are not accepted by my remote server.</p>
  
  <p>Do I have any other good alternatives?</p>
  
  <p>EDIT: Explained why addingPercentEscapesUsingEncoding and the like don't work for me here.</p>
