Confirmed here (HP-UX 10.20), even using the approved "stuff the RE into
a variable" workaround that fixes most =~ problems:

imadev:~$ bash-4.1.7     
imadev:~$ re=$'o\001world$' string=$'hello\001world'; [[ $string =~ $re ]] && 
echo match
imadev:~$

It works fine with Ctrl-B for whatever reason:

imadev:~$ re=$'o\002world$' string=$'hello\002world'; [[ $string =~ $re ]] && 
echo match
match
imadev:~$

I get the same results with bash 4.1.9 and with bash 4.2.7.
