I saw this. I was running some old scripts and st was printing garbage
characters (the diamond question mark) whenever a C1 byte came through.
Turns out those bytes are not valid UTF-8 so st was showing U+FFFD
instead of ignoring them.

check the behaviour before and after the patch:
        $ printf "\xef\xea\xek\xee"

Should not break anything.
