I created a duplicate of this item and it had the same error. Next I deleted the abstract and OAI-PMH worked. Then I replaced (𝝌² ) with (Χ²) in the abstract and that worked, too. So, finally, I deleted the duplicate item, leaving http://hdl.handle.net/10919/86579.

Another item, http://hdl.handle.net/10919/85889, failed with 𝝰4 and 𝝰5 in dc.description.abstract. I replaced them with α4 and α5 and they harvest in https://vtechworks.lib.vt.edu/oai/request?verb=GetRecord&metadataPrefix=qdc&identifier=oai:vtechworks.lib.vt.edu:10919/85889 correctly.
