1.<globalization
            requestEncoding="gb2312"
            responseEncoding="gb2312"
   />

或者

<META http-equiv="content-type" content="text/html; charset=gb2312">


2.下载文件时指定文件名,中文的文件名出现了乱码?

Response.AddHeader("Content-Disposition", "attachment; filename="+HttpUtility.UrlEncoding(filename.ToString ()));

3.如何识别字符串中是否包含韩文

http://search.csdn.net/Expert/topic/2456/2456407.xml?temp=.5485498

如果只有英文和韩文
/*******该函数返回字符串中除英文外的字符*********/
create function test(@a varchar(20))
returns varchar(20)
as
begin
   declare @b varchar(20),@i int
   set @b = ''
   set @i = 1
   while @i<= len(@a)
   begin
       if Upper(substring(@a,@i,1)) not between 'A' and 'Z'
           set @b = @b + substring(@a,@i,1)
 set @i = @i+1
   end
   return @b
end

Select dbo.test('aabc12dsa451')

                    
--------------------
12451

--1.有关多国文字的,一定要用UNICODE判断!
--2.韩文UNICODE分两断: 12592->12687  44032->55203
相关网站:http://www.buja.8u8.com/eeeeee.htm


create function hw(@str Nvarchar(100))
returns int
as
begin
declare @a int
set @a=0
while @str<>'' and @a=0
  begin
  set @a=(case when unicode(left(@str,1)) between 12592 and 12687
                 or unicode(left(@str,1)) between 44032 and 55203
               then 1
               else 0 end)
  set @str=right(@str,len(@str)-1)
  end
return @a
end 

--调用:
declare @a nvarchar(100)
set @a=N'abc中갃国123'
select dbo.hw(@a)

--return: 1


set @a=N'abc中国123'
select dbo.hw(@a)

--return: 0

4.为什么文件读出来的中文字符是乱码?

System.IO.StreamReader m_fs = System.IO.File.OpenText(Hfile_SelectFile.Value);
改为
System.IO.StreamReader m_fs = new System.IO.StreamReader(Hfile_SelectFile.Value,System.Text.Encoding.GetEncoding("gb2312"));

5.JMAIL 发邮件附件或者没有或者在正文中是乱码

6.怎么解决查询字符串中文乱码问题?

查询内容用Server.UrlEncode编码

string url ="http://localhost/test/test.aspx?a="+ Server.UrlEncode("张三");

-->Server.UrlDecode()
