 * in addition to returning false from failing operations,
 * the implementation must prevent unexpected behavior (e.g., crashes)

     * The returned buffer is only valid until the next operation

     *
     * After writing at most *resultCapacity char16_ts, call appendString() with the

     * Many appendString() implementations will avoid copying char16_ts if this function
     * returned an internal buffer.
     *
     * Partial usage example:
     * \code
     *  int32_t capacity;
     *  char16_t* buffer = app.getAppendBuffer(..., &capacity);
     *  ... Write n char16_ts into buffer, with n <= capacity.

     * \endcode

     *
     * If the Appendable allocates or reallocates an internal buffer, it should use
     * the desiredCapacityHint if appropriate.
     * If a caller cannot provide a reasonable guess at the desired capacity,
     * it should pass desiredCapacityHint=0.
     *
     * If a non-scratch buffer is returned, the caller may only pass
     * a prefix to it to appendString().
     * That is, it is not correct to pass an interior pointer to appendString().
     *
     * The default implementation always returns the scratch buffer.
