There is some mismatch. First, that is in `gcc` and this is in `libcpp`.
Second, `pretty-print.cc`'s implementation:
- fails on an empty string;
- accepts extended-length (5+-byte) encodings which are invalid Unicode;
and
- decodes codepoint-by-codepoint instead of just validating the entire
string.
