Unicode Mail List Archive: RE: How many characters? (original) (raw)

Next message: Jony Rosenne: "RE: Hebrew script in IDN"

[I replied earlier, but that response seems to have gotten lost.]

I think both you and Ken are wrong re 4.1. For the BMP, I did a hand count of Cf characters, and came up with 33, not 31 or 35. I also did counts on various categories of graphic characters and got the following:

Alphabetics, Symbols: 12,497
Han (URO): 20,927
Han Extension A: 6,582
Han Compatibility: 467
Hangul Syllables: 11,172
Total Graphic characters: 51,642

Thus, I get the following for 4.1:

Unicode 4.1:

51640 graphic characters assigned (BMP)
35 format control characters assigned (BMP)
65 control characters assigned (BMP)
6400 private use characters assigned (BMP)
2048 surrogate code points designated (BMP)
34 noncharacter code points designated (BMP)
5314 reserved code points (BMP)
45875 graphic characters assigned (supplementary planes)
105 format characters assigned (supplementary planes)
131068 private use characters assigned (supplementary planes)
32 noncharacter code points designated (supplementary planes)
871496 reserved code points (supplementary planes)
------------------------------------------------------------------
1114112 code points altogether
