> Method in question:
> {code}
> public static byte[] toUTF8(CharArr out) {
>     byte[] arr = new byte[out.size() << 2]; // is 4x the real worst-case upper-bound?
>     int nBytes = ByteUtils.UTF16toUTF8(out, 0, out.size(), arr, 0);
>     return Arrays.copyOf(arr, nBytes);
>   }
> {code}
> The byte array should be at least out.size() * 3.
