Character encodings for special characters sent through DataCite API

I am trying to figure out the best way to encode special characters like copyright ©, registered trademark Ⓡ, and degree symbol ° when pushing metadata to DataCite from our system via the MDS or REST API. I believe our system is storing them as HTML encodings (e.g., &code;). But for some reason that doesn’t make it to DataCite properly. Any suggestions would be greatly appreciated!


Hi @mlangseth - I think if you use HTML encodings that should still be stored by DataCite. Do you have example metadata you could share? You can also email us at with an attachment (either XML or the JSON payload you’re sending to the REST API).
