The dirty little secret of std::wstring is that it does not actually deal
with non-ASCII characters on all platforms.  On some platforms wchar_t is
8-bit just like char!  You should avoid using wstring and wchar_t for this
reason; define your own types that are exactly what you need.

For protocol buffers, we take the convention of using regular 8-bit chars
but always using UTF-8 encoding.
