printf appears to typically accept escaped hexadecimal octets of the
form \nXX, where XX are two hexdigits.
out of several printf implementations (including /usr/bin/printf and the builtins on many other shells), dash alone simply passes those
characters through to output:
```
0 dkg@bob:~$ dash -c "printf '\xd5'" | hd
00000000 5c 78 64 35 |\xd5|
00000004
0 dkg@bob:~$ bash -c "printf '\xd5'" | hd
00000000 d5 |.|
00000001
0 dkg@bob:~$ posh -c "printf '\xd5'" | hd
00000000 d5 |.|
00000001
0 dkg@bob:~$ zsh -c "printf '\xd5'" | hd
00000000 d5 |.|
00000001
0 dkg@bob:~$ fish -c "printf '\xd5'" | hd
00000000 d5 |.|
00000001
0 dkg@bob:~$ /usr/bin/printf '\xd5' | hd
00000000 d5 |.|
00000001
0 dkg@bob:~$
```

suggests that perhaps \xNN isn't a POSIX standard, so maybe it's within
spec for dash to ignore it. But it might also be nice to make it work
the way everyone else expects.
