- * specified by @a dest and @a size. @a size must be non-zero and the string
- * written will always be well-formed. Surrogate pairs also supported.

- * @param dest  Destination buffer.
- * @param size  Size of the destination buffer.
- * @param src   Source utf16 string.

- * @return EOK, if success, negative otherwise.
