$ rm foo rm: remove regular empty file ?foo??Why does it show a question mark instead of an apostrophe?
Running the same command with a different or no LANG setting seems to help:
$ LANG=C rm foo rm: remove regular empty file 'foo'? $ LANG="" rm foo rm: remove regular empty file 'foo'? $ echo $LANG en_US.UTF-8I usually start my screen sessions with

screen(1)started in UTF-8 mode and still have character issues? Weird. But then I remembered: I use
-Uonly when starting the
screensession, not when resuming the session:
% screen -US MySession $ echo $LANG; rm foo en_US.UTF-8 rm: remove regular empty file 'foo'?Upon resuming the session with
"screen -dr"the question marks were back again. Resuming with
A more simple test may be just to print some characters:
$ echo -e '\xe2\x82\xac' € $ screen -S foo # echo -e '\xe2\x82\xac' � ^ad $ screen -Udr foo # echo -e '\xe2\x82\xac' â¬And conversely, this time we start our session in UTF-8 mode:
$ screen -US foo # echo -e '\xe2\x82\xac' € ^ad $ screen -dr foo # echo -e '\xe2\x82\xac' ?
