/** @brief C++ string class.
*
* This is a C++ string class that does not depend on anything else except IPRT
* memory management functions. Semantics are like in std::string, except it
* can do a lot less.
*
* Note that RTCString does not differentiate between NULL strings
* and empty strings. In other words, RTCString("") and RTCString(NULL)
* behave the same. In both cases, RTCString allocates no memory, reports
* a zero length and zero allocated bytes for both, and returns an empty
* C-style string from c_str().
*
* @note RTCString ASSUMES that all strings it deals with are valid UTF-8.
* The caller is responsible for not breaking this assumption.
*/

/** @remarks Much of the code in here used to be in com::Utf8Str so that
* com::Utf8Str can now derive from RTCString and only contain code
* that is COM-specific, such as com::Bstr conversions. Compared to
* the old Utf8Str though, RTCString always knows the length of its
* member string and the size of the buffer so it can use memcpy()
* instead of strdup().
