[...] There has been a workaround in Mutt, so that this should no longer occur in Mutt (but possibly in other curses applications). Yesterday I received another spam yielding the same kind of issue, this one with U+061C ARABIC LETTER MARK characters: https://gitlab.com/muttmua/mutt/-/issues/413 The issue can be reproduced in the following way without needing Mutt: In a 80-column xterm, execute "screen bash", then for i in `seq 60` ; do printf 'a\u061c\u061c' ; done ; echo then reduce the terminal window by one line. This has the effect to duplicate the prompt and move the status line 2 lines above.
