Yeah, I guess so, it'll be a font thing.

I suppose you initially received the message through IMAP. Could you
find the message in the local cache, please? It might look differently
than the one you sent me privately. You can find it under:
   ~/.cache/evolution/mail/<imap-account-uid>/folders/.....
I'd search the files for something unique, like the message ID header
value, which contains "20180927174114.0DEFF2027154@" (quotes for
clarity only) in the message you sent me.

I've some ancient versions of IMAP servers and I tried the message
there, by drag&dropping the test message from an On This Computer
folder to the respective account folder and this is the result:
both dovecot 2.2.18 and courier 0.75.0 show the message properly, cyrus
2.4.17 replaced those Unicode letters with XXXX and XXXXXX
respectively. Thus in case of Cyrus it was the server decision, not the
client decision. My versions are very ancient, maybe your (I suppose)
more recent Courier also does some modifications to the message, as you
suggested.
