Native API : Get dataset citation result not unescaped

The output from the get dataset citation command (https://guides.dataverse.org/en/latest/api/native-api.html#get-citation) retrieves an escaped citation.

  while it is not the case with other API commands e.g. https://demo.dataverse.org/api/v1/datasets/:persistentId/versions/:latest?persistentId=doi:10.70122/FK2/ACDRRT : Author Name Éxàmpl€ appears as Éxàmpl€.

Are you thinking about creating a pull request for this issue?
Maybe depending on the complexity to unescape the text :)

Start with the Native API get-citation endpoint and compare its response for the supplied persistent identifier with the regular dataset-version response. Trace where the citation output is generated and verify that names such as Éxàmpl€ are returned unescaped, matching the expected behavior described in the issue.
