[哈啦]

我有一個文件，很奇怪，那個文件執行時，所有填上中文的都可以順利顯示，唯獨裡面一塊「內容簡介」裡填上中文，出來時卻成為亂碼？整個網站都已採utf-8編碼，不知為何會出這種狀況？

文件如下，紅色那塊出來的內容，填上中文會成為亂碼：

{include file="header.tpl"}
{literal}
<script>
function checkform()
{
if (document.video.titletext.value == '') {
alert('Please Enter A Title');
return false;
}
else if (document.video.descriptiontext.value == '')
{
alert('Please Enter A description');
return false;
}
else if (document.video.authortext.value == '')
{
alert('Please Enter A Author');
return false;
}
else if(!document.video.picture[0].checked && !document.video.picture[1].checked && !document.video.picture[2].checked) {
alert('Please Choose A Screenshot');
return false;
}
// If the script gets this far through all of your fields
// without problems, it's ok and you can submit the form

return true;
}</script>
