Questions like this remind me how little I understand font handling. I read mail in mutt in xterm in fvwm in X, currently in buster, and I see four glyphs. If I save the email in a file, then I see the same glyphs in less etc. The font that I'm using in the xterm is fonts-hack/fonts-hack-otf/fonts-hack-ttf/fonts-hack-web, whichever of those is pulled in by xterm -fa hack -fs 16 …. If I type xfd -fa hack, I can only display as far as 0x00feff, which is far short of all but LOWER RIGHT PENCIL, and even that glyph is displayed in xfd as an empty box. So it would appear that something is performing font substitution in the xterm. Hack is a pretty sparsely populated font AIUI. A windowed emacs -fn terminus-18 displays the pencil, and replaces the others by boxes containing the appropriate hex codes, 01f471, 01f3fb, and 01f517. xfd -fn terminus-18 displays the pencil's glyph as ? (and doesn't display a sufficient range to reach the others). Running less in xterm -fn terminus-18, I get a single-width blank space for the pencil, and double-width ? for the others. In case it matters, /etc/default/console-setup contains CHARMAP="UTF-8" CODESET="Uni2" FONTFACE="Terminus" FONTSIZE="16x32" A VC displays solid diamonds for all of them. I do have some noto packages installed (fonts-noto-hinted pulls in fonts-noto-core, fonts-noto-mono and fonts-noto-ui-core in buster), but don't know what's in them. When I use xfd on them, it always displays DejaVu instead, and fc-list noto returns nothing. (fonts-recommended is new in bullseye.) I wrote /four/ glyphs, but it sounds as if Celejar sees three, the first one being coloured with some sort of skin tone. My second glyph, 🏻, is a half-tone box with three lines of dots inside, of 3, 4 and 3 dots. Cheers, David.
