The HP-UX one is actually OK with that. The error is from an old gnu
coreutils (2.0), and it's complaining because there no leading zero,
which POSIX says octal escapes have:
https://pubs.opengroup.org/onlinepubs/9699919799/utilities/printf.html
"""
The following <backslash>-escape sequences shall be supported:
[...]
"\0ddd", where ddd is a zero, one, two, or three-digit octal number
that shall be converted to a byte with the numeric value specified by
the octal number
"""
$ /usr/local/bin/printf '\03' | od -x
0000000 0300
0000001
$ /usr/local/bin/printf '\3' | od -x
/usr/local/bin/printf: \3: invalid escape
0000000

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
