-Note: This section will go away when {{bug|963556}} lands.
+MozNDEFRecord follows the NFC Forum format, and NfcUtils in {{bug|963556}} will provide some basic constants and utility functions to create and parse NDEF records.
- MozNDEFRecord has Uint8Array fields containing binary data. In the following examples, we'll just refer to this helper function to convert javascript strings to Uint8Array buffers.
-  var NfcUtils = {
-    fromUTF8: function nu_fromUTF8(str) {
-      var buf = new Uint8Array(str.length);
-      for (var i = 0; i < str.length; i++) {
-        buf[i] = str.charCodeAt(i);
-      }
-      return buf;
-    }
-  }
