Andre submitted 2 years ago DM_VIDEO improvements for UEFI applications using UEFI's EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL but did not follow with suggested changes. This series takes care of the UTF-8 support which required to draw symbol and box drawing characters used by UEFI applications like grub2 and sd-boot correctly.
Compared to Andre's version this version has the following changes: - use and extend existing conversion functions from lib/charset.c - convert first to UTF-32 to support the truetype console as well - conversion is conditional on CONFIG_EFI_LOADER - use escape sequences in tests as proposed by Heinrich
