And it's worth noting that the above paragraph states a "solution" to
the problem that is: "How to make it possible to use UTF-8 without
declaring it?"

Adding autodetection wouldn't actually force authors to use UTF-8, so
the problem Faruk stated at the start of the thread (authors not using
UTF-8 throughout systems that process user input) wouldn't be solved.
