Unicode characters beyond U+FFFF. Unicode covers the entire range of code points (informally characters, don't worry about the technical difference) from U+0000 to U+10FFFF. The part following the "U+" is the numeric ordinal value, written in hexadecimal. Some older versions of Unicode only included 2**16 == 65536 distinct characters, but many years ago Unicode was extended far beyond that number. But the first 65536 characters are called the "Basic Multilingual Plane". All the rest are in the "Supplementary Multilingual Planes", which being a mouthful to say and write, often gets abbreviated as "astral planes". Hence the characters themselves are called "astral characters". Even today, some programming languages and systems have difficulty dealing with characters that require more than two bytes. -- Steven -- https://mail.python.org/mailman/listinfo/python-list
