Great catch! I haven't looked at it from that angle.
However, I'm using escape sequences like the one above to include parts (2 to 32 bytes) of a binary protocol . They are sent out on the serial interface.
Replacing all printable characters in the sequence would be cumbersome and error prone. Can such warnings be disabled?
