Print std::u8string, std::u16string, and std::u32string as string literals Previously, these types were printed as "{ U+123, U+456, U+789 }". However, printed output in that form is difficult to compare against any literals that might be defined in code. Instead, just treat these types like std::string and std::wstring, escaping non-ASCII characters with a hexadecimal escape sequence. The tests have also been updated to cover the new functionality: as a bonus, the tests now also pass with the MSVC toolchain. Internally, the code has been reorganized to primarily operate in terms of char32_t, under the assumption that char32_t will always be at least as big as wchar_t. While that assumption is currently true, perhaps it won't be in the future... PiperOrigin-RevId: 3640331321a8ecf18
