Incorrect content-length in callback.js when body contains non-ascii characters

Incorrect content-length in callback.js when body contains non-ascii characters

callback.js, line 46 is:

     'Content-Length': data.length

callback.js, line 46 should be:

    'Content-Length': Buffer.byteLength(data)

You are right, the data object should be converted to a buffer first to determine the length of the content.

The RFC specifies that the content-length is specified as the number of octets (number of bytes) and not as the length of the string.

Would you be willing to provide a PR for this? I currently don't have a lot of time to spare..

Sure, will do it in few days!
