if both sides of the ^ operator are integers, it will naturally convert the binary to do XOR operations, but what if they are all strings?

if it is two characters, it depends on whether the programming language you are using supports syntax:
there are operator overloading methods for ^ operators that match char ^ char .
if syntax allows, it depends on how the overloaded method is defined.
In general, the ASCII code values of arg1 and arg2 are taken directly and then the number ^ number operation is continued.
but for a string, it should not work unless you manually overload the ^ operator to support it, or how to take the number value for a string greater than 1 is undefined.
