You are correct: there is a typo in that line: it should be 0x800 instead of
0x400. Thank you for bringing it to our attention.
P.S. A nice way to remember the number of bits in each form of UTF-8 is that
it is 5 bits / byte + 1, plus another 1 in the case of the single byte form.
That is, the 1-byte form gives you 7 bits, the 2-byte form gives you 11
bits, 3 byte gives 16, 4 byte gives 21.
