 ## Binary data
-QR Codes can hold arbitrary byte-based binary data. If you attempt to create a binary QR Code by first converting the data to a JavaScript string, it will fail to encode propery because string encoding adds additional bytes. Instead, you must pass a [`Uint8ClampedArray`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8ClampedArray) or compatible array, or a Node [Buffer](https://nodejs.org/api/buffer.html), as follows:
