From 33b28998119004f89a662fb3f96e49d0bd9b99a0 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Sat, 16 Mar 2024 22:50:22 +0100 Subject: [PATCH] efi_selftest: Add box drawing character selftest UEFI applications rely on Unicode output capability, and might use that for drawing pseudo-graphical interfaces using Unicode defined box drawing characters. Add a simple test to display the most basic box characters, which would need to be checked manually on the screen for correctness.
