UTF-8 is an 8-bit encoding, which means there are no issues with byte order in UTF-8. Each byte in a UTF-8 byte sequence consists of two parts: Marker bits (the most significant bits) and payload bits. The marker bits -are a sequence of zero to six 1 bits followed by a 0 bit. Unicode characters are +are a sequence of zero to four ``1`` bits followed by a ``0`` bit.
