QString correctly encodes UTF-16 surrogate pairs as their UTF-8 sequences,
like you said above.
But that was not the question. The question was whether the surrogate pair
0xD83F 0xDFFF should be considered improper for UTF-8 encoding and dropped?
And the opposite: should the UTF-8 sequence 0xF0 0x9F 0xBF 0xBF be considered
incorrect and dropped?
