I don't think this is a very good change. It's easy to mistake those \U codes as text. If someone really want to see the code, they can use M-x describe-char. All terminal emulators broke after this change. Anyway, I workarounded it by modifying glyphless-char-display with the following in terminal buffers: =2D-8<---------------cut here---------------start------------->8--- (set-char-table-extra-slot glyphless-char-display 0 'thin-space) =2D-8<---------------cut here---------------end--------------->8--- This shows a single space character. Though ambitious, at least it save the terminals. =2D-=20 Akib Azmain Turja Find me on Mastodon at @akib@hostux.social. This message is signed by me with my GnuPG key.
