The string “ñ” or “ã” not worked cause the keyboard layout of remote machine is not configured to ABNT.
So I zipped the frappe-bench folder and downloaded it on my local machine, and ran: find . -name '*.py' | grep ã
That’s worked! Found it an app folder named by sistema_de_notificação_eletrônica_de_multas then renamed to sistema_de_notificacao_eletronica_de_multas
Thank you so much for help @tmatteson and @clarkej!!
