In qrcode 1.5.4,react native hermes don't support TextEncoder().encode(data).

[Hao-yiwen]

function ByteData (data) {
  this.mode = Mode.BYTE
  if (typeof (data) === 'string') {
    this.data = new TextEncoder().encode(data)
  } else {
    this.data = new Uint8Array(data)
  }
}

This js code can't work in react-native hermes engine. data = encodeUtf8(data) work great.
