	std::size_t size_as_wide(const char * in, std::size_t size, error_code &)

	const char * from_next = from;
	std::size_t char_count = 0u;
	while (from_next < from_end)

	++char_count;
	unsigned int octet_count = get_octet_count(*from_next);
	// The buffer may represent incomplete characters, so terminate early if one is found
	if (octet_count > static_cast<std::size_t>(from_end - from_next))
	break;
	from_next += octet_count;
	}
	return from_next - from;
	}

char_count doesn't seem to be used anyhow. Compilers complain about it.
