* Note that embedded NULs, or lack of a NUL terminator

* will be reported to this effect.
*
* If decoding is successful, the decoded data will
* be returned and @out_len set to indicate the
* number of bytes in the decoded data. The caller
* must use g_free() to free the returned data when
* it is no longer required.

* Returns: the decoded data or NULL
