Consider printf "%-40s : %s\n", $_->@* for @rows; The intention is to print a nice neat table on the terminal. This works fine in ASCII but gets all confused if any ->[0] element contains Unicode text. While Perl will count in Unicode codepoints, this won't help if there are combining chars (because combining chars count as codepoints but do not consume terminal columns), or if there are any emoji or other double-width characters (because these single graphemes count as two columns). I propose a new printf flag, perhaps `|`, to tell (s)printf to count these strings by terminal width instead. Thus printf "%-|40s : %s\n", $_->@* for @rows; would now print a neat table even in the presence of Weird Unicode. If no objections I'll write up an RFC. -- Paul "LeoNerd" Evans leonerd@leonerd.org.uk | https://metacpan.org/author/PEVANS http://www.leonerd.org.uk/ | https://www.tindie.com/stores/leonerd/Thread Next
