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 to Unicode code points for truetype console support
- conversion is conditional on CONFIG_CHARSET
- use escape sequences in tests as proposed by Heinrich

Heinrich
