Your claim is incorrect.

hobbit:~$ printf %s $'\1abc' | hd
00000000  01 61 62 63                                       |.abc|
00000004
hobbit:~$ printf %s $'\10abc' | hd
00000000  08 61 62 63                                       |.abc|
00000004

\1 and \10 are both recognized as octal values.  This works in bash 5.2,
5.3 and 2.05b, and though I didn't test any other versions just now,
I'm pretty confident it didn't change in between.
