Cardano-cli ScriptDataBytes object

Hi all,

Does anyone know and able to explain to me how the ScriptDataBytes value is encoded as part of a query of an address as part of a cardano-cli call return?

i.e. ReferenceTxInsScriptsInlineDatumsInBabbageEra is returned with the datum encoded.

but there are elements such as \NUL and \ETB.

What I’m failing to understand how these related to the CBOR/CDDL structures?

i.e. is there a mapping standard if this is for human readable values? or is this following a standard encode/decode specification I’m not aware of?

If I get the datum from dbsync, all is well. I’m just wondering if the datum should be decodable from cardano-cli?

Thanks and kind regards

P.S. maybe an example would help:

                           TxHash                                 TxIx        Amount

Looking at the fortuna datum as a good example. From this, I know ScriptDataBytes of

However, I don’t get how cardano-cli is encoding this?!
