So long as they're differentiated. I don't make use of the following, so they're not important to me, but it might be worthwhile to handle these: U+2BBD BALLOT BOX WITH LIGHT X U+2718 HEAVY BALLOT X U+2717 BALLOT X So far as I'm aware, there's no way to map non-BMP UTF8 (e.g. U+1F5F6 BALLOT BOLD SCRIPT X) into the console Unicode->font table, since it only accepts UCS-2 (fixed 16-bit). I'm interested in putting together the necessary kernel work to address this, but until then it's not a thing. Will this work be going upstream? I'm not clear on whether you're the upstream maintainer, or just Debian's. -- nick black -=- https://www.nick-black.com to make an apple pie from scratch, you need first invent a universe.

While I've got you here, while the case isn't quite as clear-cut for these two, I'd suggest mapping U+2612 BALLOT BOX WITH X -> U+0058 LATIN CAPITAL LETTER X and U+2610 BALLOT BOX -> U+002D HYPHEN-MINUS or, if you prefer, U+004F LATIN CAPITAL LETTER O Right now they render as the same missing glyph, which does nothing good for anybody =]. I add these two mappings on the fly in Notcurses for my multiselector widget. -- nick black -=- https://www.nick-black.com to make an apple pie from scratch, you need first invent a universe.

Anton Zinoviev left as an exercise for the reader: I tested your Arabic-Fixed16 and Lat15-Terminus16, I'm pretty sure. First, I verified that the targeted UTF-8 was being rendered as the absent glyph, as expected. I then ran "setfont FONTFILE", and verified that the UTF-8 was properly being rendered as the base of its class. Except for one: the weird "big foreslash" is being mapped to a percent sign instead of a foreslash. Everything else looks correct, and seems a big improvement. -- nick black -=- https://www.nick-black.com to make an apple pie from scratch, you need first invent a universe.

To be more precise, U+2571 BOX DRAWINGS LIGHT DIAGONAL UPPER RIGHT TO LOWER LEFT ought be getting mapped to U+002F SOLIDUS aka '/', but is instead being mapped to U+0025 PERCENT SIGN aka '%'. I believe you've mapped to font index 37 when you want font index 47. -- nick black -=- https://www.nick-black.com to make an apple pie from scratch, you need first invent a universe.

Bug#965029: console-setup: fonts missing numerous unicode->font mappings for box-drawing characters
Package: console-setup Version: 1.196 Severity: wishlist Tags: upstream Dear Maintainer, While working on Notcurses (https://notcurses.com), I realized that numerous Unicode Box-Drawing Characters resolve to the missing glyph (U+FFFD), despite being well-simulated by glyphs present in the font. I suggest that these Unicode->font mappings be added to the various psf files. Notcurses currently adds them (if not already present) at application start time, and I can verify that it significantly improves the console experience. I'm happy to make these patches and send them upstream, but Anton Zinoviev requested that I file a bug here. I consider the following wide strings to be acceptable fallback sets (taken from Notcurses src/lib/linux.c): .ws = L"/╱", .ws = L"\\╲", .ws = L"X╳", .ws = L"└┕┖┗╘╙╚╰", .ws = L"┘┙┚┛╛╜╝╯", .ws = L"┌┍┎┏╒╓╔╭", .ws = L"┐┑┒┓╕╖╗╮", .ws = L"─━┄┅┈┉╌╍═╼╾", .ws = L"│┃┆┇┊┋╎╏║╽╿", .ws = L"├┝┞┟┠┡┢┣╞╟╠", .ws = L"┤┥┦┧┨┩┪┫╡╢╣", .ws = L"┬┭┮┯┰┱┲┳╤╥╦", .ws = L"┴┵┶┷┸┹┺┻╧╨╩", .ws = L"┼┽┾┿╀╁╂╃╄╅╆╇╈╉╊╋╪╫╬", Let me know how I can make myself useful. -- System Information: Debian Release: bullseye/sid APT prefers unstable APT policy: (300, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 5.7.8nlb (SMP w/64 CPU threads) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_WARN, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages console-setup depends on: ii console-setup-linux 1.196 ii debconf 1.5.74 ii keyboard-configuration 1.196 ii xkb-data2.29-2 console-setup recommends no packages.
