title: Visual Studio Code snippet invalid control character
body: <p>I have the following user snippet:</p>
  
  <pre><code>{
  /*
      // Place your snippets for JavaScript React here. Each snippet is defined under a snippet name and has a prefix, body and 
      // description. The prefix is what is used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
      // $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. Placeholders with the 
      // same ids are connected.
      // Example:
      "Print to console": {
          "prefix": "log",
          "body": [
              "console.log('$1');",
              "$2"
          ],
          "description": "Log output to console"
      }
  */
      "Small comment": {
          "prefix": "//=",
          "body": [
              "// ===================================",
              "// ${1:COMMENT}",
              "// ==================================="
          ],
          "description": "Small comment"
      }
  }
  </code></pre>
  
  <p>I get the following error on the second body line:</p>
  
  <p><code>Invalid characters in string.  Control characters must be escaped.</code></p>
  
  <p>I thought that <code>${1:somestring}</code> was a valid placeholder.  What am I doing wrong in constructing this snippet?</p>
