Hi, I'm using older bash 3.2.39, so please forgiveme if in your newer
bash this issue does not arise.
0x00 and 0x0a has no output in printf "%q"
$ for i in {0..9} a; do printf "%q\n" "`echo -en \"\x0$i\"`"; done
''
$'\001'
$'\002'
$'\003'
$'\004'
$'\005'
$'\006'
$'\a'
$'\b'
$'\t'
''

As for NUL out outputting anything in your result, the cause is C-strings.
Arguments are C-strings and those are delimited by NUL bytes. Therefore, the
NUL byte that you're putting in it is actually marking the end of the string.
So the argument ends BEFORE your NUL byte. So it's empty.
