 //! \param[in] source A pointer to a `NUL`-terminated string of char16 data. The
 //!     `NUL` terminator must be a `NUL` value in a char16 unit, not just a
 //!     single `NUL` byte.
 //! \param[in] length The length of the \a destination buffer in char16 units,
 //!     not bytes. A maximum of \a `length - 1` char16 units from \a source will
 //!     be copied to \a destination.
 //!
 //! \return The length of the \a source string in char16 units, not including
 //!     its `NUL` terminator. When truncation occurs, the return value will be
 //!     equal to or greater than than the \a length parameter.
