I cannot find GB18030 stardard in local library, neither can I find it anywhere on the Internet. I wish to know the stardard itself.
GB18030 contains about 27000 characters. CJK contains about 21000 characters and CJK Extension A 6000 characters. (i don't remeber the actual number.) It seems GB18030 is simple a combination of the later two, only different in order. Is it true?
