Problem:
When AWX (Ansible Tower) sync its inventory or when manually generating an “Ansible Inventory” Report template, with facts, if any of those facts contains a non ascii character and you try to export the template in Json, you’ll receive an error similar to :

(Encoding::UndefinedConversionError): “\xC3” from ASCII-8BIT to UTF-8

In my case, I had the following in one of my host :

ec2_userdata :
"then rm /bootstrap.donefi# Récupération du répertoire courant et du répertoire "

Which caused the problem.
Exporting in anything else but Json works without problem.

Expected outcome:
No error when generating the report
