title: Do curly braces inside json string objects need to be escaped?
body: <p>This string is part a JSON object/file:</p>
  
  <pre><code>"Mask" : "{0}(CASE WHEN {1} = {2} THEN {3} ELSE 0 END) {4}"
  </code></pre>
  
  <p>Will JSON recognize that as part of standard JSON notation or do I need to escape those curly braces s somehow?</p>
  
  <p>If so, how does one escape curly braces in JSON?</p>
