---------------------------------------------

the entry in CHANGES.txt
> Utils.toUTF8 uses shorter buffer than necessary for holding UTF8 data

> Method in question:

> 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.
