an é (e with accent) can also be written as e+\u0301. the first form is NFC, the second NFD. when logging in, we transform usernames (email addresses) to NFC. so both forms will be accepted. if a client is using NFD, they can log in too. for passwords, we apply the PRECIS "opaquestring", which (despite the name) transforms the value too: unicode spaces are replaced with ascii spaces. the string is also normalized to NFC. PRECIS may reject confusing passwords when you set a password.
