From bfc2dd53812f7946b61c18e915118fb7aad12e6d Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Sat, 6 Apr 2019 20:59:24 +0200 Subject: [PATCH] efi_loader: correct CTRL-A - CTRL-Z console input In the extended text input protocol CTRL-A - CTRL-Z have to be signaled as Unicode characters a-z or A-Z depending on the shift state and not as 0x01 to 0x1a. Update Python unit test. This patch is required for using the EFI shell `edit` command.
