     * The returned buffer is only valid until the next operation

     *
     * After writing at most *resultCapacity char16_ts, call appendString() with the
     * pointer returned from this function and the number of char16_ts written.
     * Many appendString() implementations will avoid copying char16_ts if this function
     * returned an internal buffer.
     *
     * Partial usage example:
     * \code
     *  int32_t capacity;

     *
     * 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().
