The Number Of Characters In Unicode

Ken Whistler provided this numeric breakdown of the code points in the Unicode Character Standard, showing how many are assigned to each character type, how many are reserved for future use, and the number remaining. Links to the Unicode glossary are provided where each Unicode term is initially used. An index of Unicode terminology with glossary links is also provided.

For more information about how scripts are allocated in Unicode, and which scripts may be forthcoming, see the Unicode Consortium's web page Roadmaps to Unicode. To identify if a particular character is in Unicode, see the page Where is my Character?. To understand the value of a comprehensive, universal character standard, see I18nGuy's Benefits of the Unicode Standard.

The number of characters in the Unicode Character Standard version 3.2 is 95,221.

The number 95,221 is derived from: 95,156 graphic characters + 65 control codes.
That corresponds to the number of encoded characters, omitting private use area (PUA) characters.
The total number of assigned code points is 95,156 + 6400 + 131,068 + 65 = 232,689.
The total number of designated code points is (232,689 assigned code points) + (2048 + 34 + 32) = 234,803.
