I have modified Document#to_s to permit the inclusion of a second
encoding argument (didn't know there was a first one, eh?). It will
not change the document encoding, but will case libxml to produce a
representation of the document in the requested encoding (transcoding
it if necessary). The default for it is nil, and results in the
document's encoding.
A few other notes about UTF-16 specifically; UTF-16 will result in a
two byte lead in, UTF-16BE will not, nor will UTF-16LE. These latter
encodings are not familiar, but may or may not be of interest.
You were getting two 8bit chars and nothing else because of the
UTF-16 lead in, but it was also getting truncated because the wrong
ruby string constructor was being called (which did not use the
length returned by the libxml dump, so an ^@ was stopping the string).
In other words, it was always broken (I had not previously modified
this code), now it is less broken.
