My fault, this is what I meant to send:

bash-5.1$ str=$'contains ^A: \1'
bash-5.1$ printf '%s' "$str" | od -ta -tx1
0000000    c   o   n   t   a   i   n   s  sp   ^   A   :  sp soh        
           63  6f  6e  74  61  69  6e  73  20  5e  41  3a  20  01        
0000016
bash-5.1$ str=${str//\\\\/$'\1'} str=${str//\\n/$'\n'} str=${str//\\t/$'\t'}
bash-5.1$ str=${str//$'\1'/\\}
bash-5.1$ printf '%s' "$str" | od -ta -tx1
0000000    c   o   n   t   a   i   n   s  sp   ^   A   :  sp   \        
           63  6f  6e  74  61  69  6e  73  20  5e  41  3a  20  5c        
0000016

As you can see, the SOH character (^A, \001, etc.) in the original
string has been mangled.
