Error: Generic Exception: Error Improperly Formatted XML

Actually there is one :hotel: in
<Descricao_004>Hotel &#55356;&#57320; fim do expediente </Descricao_004>

This might be not accepted by certain xml parsers for example https://www.freeformatter.com/xml-formatter.html does not accept it.

What server do you use? I tried uploading a form with that emoji to Central and it worked well. Also please tell us what Collect version you are using.
