--- Begin Message ---Source: ncurses Version: 5.9+20140913-1 Control: affects -1 console-setup Tags: patch Severity: minor As of the current version of the Terminfo database, the ‘linux’ terminal entry implies the use of the CP437 encoding for the box-drawing characters and the like (also known as “alternate character set”, or ACS): $ nl -ba < misc/terminfo.src … 1577 linux-basic|linux console, 1578 am, bce, eo, mir, msgr, xenl, xon, 1579 it#8, ncv#18, U8#1, 1580 acsc=+\020\,\021-\030.^Y0\333`\004a\261f\370g\361h\260i\316j\331k\277l\332m\300n\305o~p\304q\304r\304s_t\303u\264v\301w\302x\263y\363z\362{\343|\330}\234~\376, (Read: acsc=+\020\,\021-\030.^Y0█`\004a▒f°g±h░i╬j┘k┐l┌m└n┼o~p─q─r─s_t├u┤v┴w┬x│y≤z≥{π|╪}£~■. And no, that’s /not/ line noise.) This is hardly a safe assumption these days, especially taking into account the widespread use of UTF-8, /including/ on ttys. (Please also note that the console-setup Debconf scripts will assume UTF-8 mode for ttys provided that the locale is a UTF-8 one, – which, I believe, are default with D-I installs.) There’s a separate ‘linux-vt’ entry that’s intended to be used when the terminal encoding is not known, or non-unibyte, and which emits ACS characters using VT100 ESC sequences instead: 1678 # This uses graphics from VT codeset instead of from cp437. 1679 # reason: cp437 (aka "straight to font") is not functional under luit. 1680 # from: Andrey V Lukyanov <[email protected]>. 1681 linux-vt|linux console using VT codes for graphics, 1682 acsc=++\,\,--..00``aaffgghhiijjkkllmmnnooppqqrrssttuuvvwwxxyyzz~~, 1683 rmacs=\E(K, rmpch@, sgr@, sgr0=\E[0m\E(K\017, smacs=\E(0, 1684 smpch@, use=linux, Unfortunately, this entry misses the ‘enacs’ capability, so its use doesn’t result in the proper ACS rendering, as in: $ export TERM=linux-vt $ tput enacs ; tput smacs ; printf %s\\n lk mj ; tput rmacs ; lk mj Expected: ┌┐ └┘ The /minimal/ solution for the issue is to fix the linux-vt entry by adding the missing ‘enacs’ capability: linux-vt|linux console using VT codes for graphics, acsc=++\,\,--..00``aaffgghhiijjkkllmmnnooppqqrrssttuuvvwwxxyyzz~~, enacs=\E(B\E)0, rmacs=\E(K, rmpch@, sgr@, sgr0=\E[0m\E(K\017, smacs=\E(0, smpch@, use=linux, This could just as well be combined with explicitly passing ‘linux-vt’ to the getty(8) invocations in the default /etc/inittab for the new GNU/Linux installations, – or similar measures for the systems using different means to start up the gettys. The “proper” solution, in my opinion, is to: • move the current variants of the ‘acsc’, ‘smacs’, ‘rmacs’ capabilities from linux-basic to a dedicated linux-cp437 entry (following the suit of linux-koi8, linux-koi8r, linux-lat); • replace them with the encoding-insensitive ‘acsc’, ‘smacs’, ‘rmacs’ variants from linux-vt, along with adding ‘enacs’ per above; • the linux-vt entry is then to be cut down to just ‘use=linux’ (and ‘sgr@’?), but otherwise retained for compatibility.
