Infinite loop: non-utf-8 character in a tag

[Bordasludovic]

Hello Mercure Team! ,

I sometimes get an error that seems to be linked to an "illegal" non-utf-8 character in a tag (unfortunately I didn't specify which one) that breaks the python script when it is executed.

Unfortunately, Mercure seems to insist on endlessly processing this file until I manually delete it from the server.

Could you add a rule so that Mercury rejects this file and stops processing it in an infinite loop?
