We will need to potentially grow the buffer before appending anything to it, because if we pass in 0 as a size then the MultiByteToWideChar just returns the size we would need. If we didn't intend to do so then we would increment our output buffers even though nothing is written. And when appending single characters (like the replacement character for an invalid sequence) we need to grow the buffer as well. We'll need this all in the next commit.
