 * @param dest      A buffer for the result string. The result will be NUL-terminated if
 *                  the buffer is large enough.
 *                  The contents is undefined in case of failure.
 * @param destCapacity The size of the buffer (number of bytes). If it is 0, then
 *                  dest may be NULL and the function will only return the length of the result
 *                  without writing any of the result string.
 * @param src       The original string.
 * @param srcLength The length of the original string. If -1, then src must be NUL-terminated.
 * @param pErrorCode Must be a valid pointer to an error code value,
 *                  which must not indicate a failure before the function call.
 * @return The length of the result string, if successful - or in case of a buffer overflow,
 *         in which case it will be greater than destCapacity.
