If you make an ASCII string then the top bits must be zero so it's not clean. If you make it a UC16 string then it has to have an even byte length. So the status is that there isn't any good way to store binary data in JS at the moment. Of course it is possible to put the data in an external object instead. > > e.g. over the weekend i wrote an an I/O library (http:// > code.google.com/p/v8-juice/wiki/PluginWhio) and i use vector<char> as > my read buffer.
