今天搞sxna,遇到了编码转换的难题，搞了一个多小时，历尽千辛万苦，总算总结了如下的汉字转换为各种UTF-8 Unicode Ansi编码的程序．不敢独享，特此奉献给各位编程爱好者！
--------------------------------------------------------------------------------
符合GOOGLE的UTF编码
汉字 经过encodeURIComponent变成 %E6%B1%89%E5%AD%97
%E6%B1%89%E5%AD%97经过decodeURIComponent变成汉字
用google搜索"汉字":
http://www.google.com/search?hl=zh-CN&q=%E6%B1%89%E5%AD%97
符合BAIDU的UTF-8编码
汉字 经过 AnsiCode 变为 %BA%BA%D7%D6
BA%BA%D7%D6 经过 DeCodeAnsi 变为 汉字
用baidu搜索"汉字":
http://www.baidu.com/baidu?word=%BA%BA%D7%D6
--------------------------------------------------------------------------------
汉字经过chinese2unicode变为汉字
汉字经过UTF2GB变为汉字
--------------------------------------------------------------------------------
test.asp 原程序如下
