EDIT The final 7 characters The last block of the Basic Multilingual Plane contains nonprintable characters but control characters for text processing.

The last 2 characters of the BMP are »Non-Characters«, they must not be used in text and even mess with this database if the thumbnail is clicked on. Come on, try it!

The second to last character is forever defined as a non-character to keep it distinguishable from the character U+FEFF, even when the bytes are switched (Little/Big Endian problem, see U+FEFF for explanation).
