echo -e "o\tx\nö\tx" | expand fails to align
I know this is a duplicate of https://debbugs.gnu.org/cgi/bugreport.cgi?bug=6934, https://debbugs.gnu.org/cgi/bugreport.cgi?bug=13957 (my own) and https://debbugs.gnu.org/cgi/bugreport.cgi?bug=28038 but I'm reporting again because 1. those issues have been marked "Severity: wishlist" which is not appropriate - guys, we have 2022 and Unicode support is essential! 2. https://lists.gnu.org/archive/html/coreutils/2020-11/msg00024.html claims the issue would have been fixed in 8.32 but it wasn't and it isn't in 9.0.
