From b4d4bac1c49d7e19dac6f29ea278df8be6e6dcd2 Mon Sep 17 00:00:00 2001 From: Ulf Jordan Date: Mon, 11 Aug 2008 20:34:28 +0000 Subject: Add support for line drawing characters and the alternate character set. This enables using the ACS_ curses macros with libpayload. The translation from ACS_ macros (or characters with attribute A_ALTCHARSET) is done using one acs map for the video console, one for serial console (xterm/vt100/vt220), and one fallback, from which an ASCII substitute is taken if the device specific map doesn't contain an entry (ie NUL).
