Detailed Description

The Utf8Iterator is a read-only input iterator, to iterate an UTF-8 string as if it were a sequence of unicode characters. When used with standard C++ algorithms, the default constructed iterator serves as an iterator pointing to the end of the logic sequence.

std::string utf8 = "Hell\303\266 W\303\266rld!";
Char oe = 0366;
int n = std::count(it, end, oe);
assert(n == 2);
