title: W2CA possible loss of data, right?
body: <p>I'm working a legacy VC++6 app that is trying to add in unicode support, i have a function that calls into a rpc call that expects and unsigned char, if I use the W2CA() macro on the string being passed in, am i correct in assuming that there is a possibility of not being able to convert some unicode strings right? for example, I believe 我们的 T+G2 would be a problem. I just ask because I'm trying to decide if would be better off writing a wchar_t version.</p>
  
  <p>thanks.</p>
