[U-Boot] [PATCH 0/2] Fix unicode handling in buildman

[Daniel Schwierzeck <daniel.schwierzeck@gmail.com>]

This series fixes and optimizes the unicode handling in buildman.
It's based on the similar series for patman and applies on top
of u-boot-dm/master.

This has been tested by forcibly adding unicode characters in
the stdout and stderr stream.

Examples:
