Description:
        [Detailed description of the problem, suggestion, or complaint.]
        The ASCII character \001 breaks the escape sequence
interpretation.
./bash -c "echo \^A\[bs\]"
        returns
^A\[bs]
        Please note the backslash remains. It should return ^A[bs].
        Note in comparison that
./bash -c "echo \^B\[bs\]"
        returns
^B[bs]
        as expected.

Repeat-By:
        ./bash -c "echo \^A\[bs\]"
where ^A is the ASCII character \001
