網(wǎng)頁中的字符編碼：
1、編碼轉(zhuǎn)換（to Unicode）
（程序代碼來源于網(wǎng)絡(luò)）
Js版
<script>
test = "你好abc"
str = ""
for( i=0; i<test.length; i++ )
{
temp = test.charCodeAt(i).toString(16);
str += "\\u"+ new Array(5-String(temp).length).join("0") +temp;
}
document.write (str)
</script>
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中我們可以用mbstring的mb_convert_encoding函數(shù)實現(xiàn)這個正向及反向的轉(zhuǎn)化。 如：
mb_convert_encoding ("你好", "HTML-ENTITIES", "gb2312"); //輸出：你好
mb_convert_encoding ("你好", "gb2312", "HTML-ENTITIES"); //輸出：你好
如果需要對整個頁面轉(zhuǎn)化，則只需要在php文件的頭部加上這三行代碼：
mb_internal_encoding("gb2312"); // 這里的gb2312是你網(wǎng)站原來的編碼
mb_http_output("HTML-ENTITIES");
ob_start(‘mb_output_handler‘);
如果沒有打開mbstring擴展，可以參考上的這兩篇文章：

2、HTML實體
HTML 4.01 支持 ISO 8859-1 (Latin-1) 字符集。
提示 實體名是區(qū)分大小寫的。
備注 同一個符號，可以用“實體名稱”和“實體編號”兩種方式引用，“實體名稱”的優(yōu)勢在于便于記憶，但不能保證所有的瀏覽器都能順利識別它，而“實體編號”則沒有這種擔(dān)憂，但它實在不方便記憶。
