You are using a local 8-bit encoding, whereas everyone else was using UTF-8. Your mailer re-encoded their messages into one of the 8-bit western encodings, whereas most people use UTF-8 these days, so while their original messages with accents came through just fine in UTF-8, your re-encoding into Western didn't display properly.
Although his email did reencode those names into ISO 8859-1 which is more likely to cause problems than cure them these days, it still displays well on my MUA (Thunderbird) because its header said "Content-Type: text/plain; charset=iso-8859-1". His email is also displaying properly in the archive <https://debbugs.gnu.org/cgi/bugreport.cgi?bug=47023#16>, as the archiving software reencodes those names back into UTF-8 and the web page uses "Content-Type: text/html; charset=utf-8" for all the emails.
Possibly your email client is programmed to ignore encodings in incoming "Content-Type" lines; that would explain the glitches you saw.
