Some terminal emulators are using iso-8859-1 semantics of soft hyphen, unicode did things differently but those terminals haven't changed. xterm printed as hyphen mlterm printed as hyphen putty printed as hyphen urxvt overprinted on previous character st not printed, no space kitty not printed, no space cool-retro-term not printed, no space sakura printed as space There's some more about this on https://jkorpela.fi/shy.html, it's all a mess. Pragmatically the simplest fix for the original problem might be if irssi filtered out soft-hyphen characters like mutt does in its "is_display_corrupting_utf8()" function: https://gitlab.com/muttmua/mutt/-/blob/master/mbyte.c#L528
