>xterm and Mac terminals disagree as to whether emoji are one column wide or two
ICU likely has an answer for that, but since xterm isn't using libicu, I would not be surprised if xterm does not have the contemporary picture of how things should be. That said, when I see https://metacpan.org/pod/Unicode::EastAsianWidth referring to U+2010 as "ambiguous-width", I'm losing all hope that there's one true answer for terminal implementations.
Perhaps we should just stop using emojis and anything exceeding cp437 altogether: I don't see the point of why `systemctl status ...` has to emit a U+25CF when U+2022 or an asterisk would have sufficed (because /usr/share/kbd/unimaps/cp437.uni traditionally mapped only that).
