中文字符的UNICODE编码是从19968到40870

[pengdali]

select code=identity(int,1,1) into #t
from
(select top 100 a=1 from syscolumns) as a,
(select top 100 a=1 from syscolumns) as b,
(select top 10 a=1 from syscolumns) as c
---select * from #t
select nchar(code),code from #t order by code

drop table #t

麻烦大力了，我随便想问问unicode和ascii的区别是什么
请问一下，判断一个字符是否是汉字或英文或其它字符($#^<>?)或全角标点(，。/)怎么判断呢？
