man 1p printf:
In addition to the escape sequences shown in the Base Definitions
volume of POSIX.1‐2008, Chapter 5, File Format Notation ('\\',
'\a', '\b', '\f', '\n', '\r', '\t', '\v'), "\ddd", where ddd is a
one, two, or three-digit octal number, shall be written as a byte
with the numeric value specified by the octal number.
printf '\xfe\xff' in an extension of some libc.
With dash:
$ printf '\xfe\xff' | xxd
00000000: 5c78 6665 5c78 6666 \xfe\xff
Correct its usage.

Notes:
Despite that dash's printf doesn't accept \x escape sequence.
My glibc box (with sh linked to dash) can run the test just fine.
But my musl box couldn't run the test, (because the header).
