The number of characters in each unicode block - unicode

Question

Does anyone know any reference showing the number of characters in each Unicode block? (in newer version such as 5.x.x or 6.0.0)
Thanks a lot.

Answer 1

http://www.unicode.org/Public/6.0.0/ucd/UnicodeData.txt contains the data you are interested in.
http://www.unicode.org/Public/6.0.0/ucd/ReadMe.txt contains some instructions and refers to http://unicode.org/reports/tr44/ for interpreting the data. In that document you should read http://unicode.org/reports/tr44/#UnicodeData.txt.

unichars
Does this answer your question:
% unichars '\p{InCyrillic}' | wc -l
256
% unichars '\p{InEthiopic}' | wc -l
356
% unichars '\p{InLatin1}' | wc -l
128
% unichars '\p{InCombiningDiacriticalMarks}' | wc -l
To include the 16 astral planes, add -a:
112
% unichars -a '\p{InAncientGreekNumbers}' | wc -l
75
If you want unassigned or Han or Hangul, you need -u:
% unichars -u '\p{InEthiopic}' | wc -l
384
% unichars -u '\p{InCJKUnifiedIdeographsExtensionA}' | wc -l
6592
You can get other information, too:
% unichars '\P{IsGreek}' '\p{InGreek}'

My uniprops and unichars should run anywhere running Perl version 5.10 or better. There’s also a uninames script that goes with them.

Answer 3

There's a list available here although it does not specific for which version of the standard it applies:
