Sorry, I am probably missing something. Let me describe how I understand your problem:
you've got V8 string which you'd like to write utf8 encoded into socket several times and you don't want to pay for conversion. Given that strings are immutable you can do the following: First time you write the string, you turn it into externalized string. Your externalized string resource now holds two buffers---original string and utf8 encoded. So on next write, you'll check that string is already external, fetch the resource from it, and write its utf8 encoded buffer into the socket. If that sounds reasonable, you might find this helpful: http://trac.webkit.org/browser/trunk/WebCore/bindings/v8/V8Binding.cpp That converts v8 string into WebCore string. yours, anton.
