From 0bbd8967830097b9141945ba960e90339c230ccb Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Wed, 9 Feb 2022 15:43:42 +0000 Subject: [console] Handle remapping of scancode 86 The key with scancode 86 appears in the position between left shift and Z on a US keyboard, where it typically fails to exist entirely. Most US keyboard maps define this nonexistent key as generating "\|", with the notable exception of "loadkeys" which instead reports it as generating "<>". Both of these mapping choices duplicate keys that exist elsewhere in the map, which causes problems for our ASCII-based remapping mechanism. Work around these quirks by treating the key as generating "\|" with the high bit set, and making it subject to remapping. Where the BIOS generates "\|" as expected, this allows us to remap to the correct ASCII value.
