It's well known around the Internet that to achieve compatibility you should
be conservative in what you send and liberal in what you accept. Applied to
JPEG: Use only Huffman coding when encoding – except maybe if you know that all
recipients can handle arithmetic coding – but support both encodings when
decoding.
