Now I need to call Buffer.length - Buffer.byteLength(str). It looks like not efficient.
And it makes hard to correctly convert chunks to string in TransformStream.

    I think you answered your own question? If you're doing partial writes, use a require('string_decoder').StringDecoder.

    Can you direct support questions to SO or help next time? Thanks.
