Ed sent his message in Unicode with NFC normalization (the é is pre-composed) and UTF-8. Tim's message contains two ?, indicating a pair of unknown characters. One possibility is that Tim's MUA (Evolution) converts that to NFD normalization and something in between chokes on that, and produces the doubled ?? instead of a single é.
FWIW, I sent a message on Sun, 22 Sep 2019 23:22:44 +0800 using Evolution 3.34.0 (3.34.0-1.fc31) as I only have a F31 Beta GNOME VM
In that message Frédéric survived.
