node.js v0.4.4 lib / net.js excerpt from the reference

412 if (! Encoding | | encoding == 'utf8' | | encoding == 'utf-8') {
413 / / default to utf8
414 bytesWritten = pool.write (data, 'utf8', pool.used);
415 charsWritten = Buffer._charsWritten;
416} else {
417 bytesWritten = pool.write (data, encoding, pool.used);
418 charsWritten = bytesWritten;
419}

I think I may have a better solution for this coming in node-websocket-server 2.0.0, which is currently in the works.

I have also made inquiries with peter griess who gave the original code for writing this data out, in the three sequential writes.
