网页中的字符编码：

1、编码转换(to Unicode)

(程序代码来源于网络)

Js版

test = "你好abc"

str = ""

for( i=0; i

{

temp = test.charCodeAt(i).toString(16);

str += "\\u"+ new Array(5-String(temp).length).join("0") +temp;

}

document.write (str)

vbs版

Function Unicode(str1)

Dim str,temp

str = ""

For i=1 to len(str1)

temp = Hex(AscW(Mid(str1,i,1)))

If len(temp) < 5 Then temp = right("0000" & temp, 4)

str = str & "\u" & temp

Next

Unicode = str

End Function

Function htmlentities(str)

For i = 1 to Len(str)

char = mid(str, i, 1)

If Ascw(char) > 128 then

htmlentities = htmlentities & "" & Ascw(char) & ";"

Else

htmlentities = htmlentities & char

End if

Next

End Function

coldfusion版

function nochaoscode(str)

{

var new_str = “”;

for(i=1; i lte len(str);i=i+1){

if(asc(mid(str,i,1)) lt 128){

new_str = new_str & mid(str,i,1);

}else{

new_str = new_str & “#” & asc(mid(str,i,1));

}

}

return new_str;

}

附：

在php中我们可以用mbstring的mb_convert_encoding函数实现这个正向及反向的转化。 如：

mb_convert_encoding ("你好", "HTML-ENTITIES", "gb2312");    //输出：你好

mb_convert_encoding ("你好", "gb2312", "HTML-ENTITIES");    //输出：你好

如果需要对整个页面转化，则只需要在php文件的头部加上这三行代码：

mb_internal_encoding("gb2312");  // 这里的gb2312是你网站原来的编码

mb_http_output("HTML-ENTITIES");

ob_start(‘mb_output_handler‘);

如果没有打开mbstring扩展，可以参考coolcode.cn上的这两篇文章：

2、HTML实体

HTML 4.01 支持 ISO 8859-1 (Latin-1) 字符集。

提示 实体名是区分大小写的。

备注 同一个符号，可以用“实体名称”和“实体编号”两种方式引用，“实体名称”的优势在于便于记忆，但不能保证所有的浏览器都能顺利识别它，而“实体编号”则没有这种担忧，但它实在不方便记忆。
