If expanding a \u (or \U) escape sequence fails, Bash replaces the
input escape sequence with a newly generated one:
$ LC_ALL=C printf %b \\U80
\u0080
Bash normalizes to a consistent result across printf/echo/$''.
Since this new sequence may by longer than the input, it can cause an
overflow in printf:
Thanks, this should use the same logic as ansicstr(), since it ends up
calling the same translation functions.
