Diacritics in the people id is causing problem for saving some records.

[rsdoiel]

When we have a diacritical in the clpid there is a problem when saving the edited record. Two example clpid are García-Javier-A and
Schröder-P. Kathy quickly identified others with a similar pattern. I can update plan ASCII clpid (e.g. myself) without a problem.

The output of cold reports the following

The HTTP HEAD, used to directory, does NOT support UTF-8. This impacted Invenio RDM recently too. Review other options for the redirect or handling the encoding differently.
