What would you expect the output to be when the input is: nôn nôn Sending that through rev (with a UTF-8 locale), I get n̂on nôn By the way, did you know the perl -l flag removes newlines on input and adds them for a print, so your command could just be: perl -lne 'print scalar reverse' And, for a unicode-aware version: perl -CDS -lne 'print scalar reverse'
