我正在为我的一个项目探索tiny mce编辑器，但我发现工具栏中的图标没有显示出来。它显示了一些unicode字符，而浏览器无法显示。这是页面的HTML代码：
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/ht/loose.dtd">
<html>
<head>
<title>HTML</title>
<script type="text/javascript" src="../js/tinymce/tinymce.min.js"></script>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<script type="text/javascript">
tinymce.init({
selector: "textarea",
plugins: [
"advlist autolink autosave link image lists charmap print preview hr anchor pagebreak spellchecker",
"searchreplace wordcount visualblocks visualchars code fullscreen insertdatetime media nonbreaking",
"table contextmenu directionality emoticons template textcolor paste fullpage textcolor"
],
toolbar1: "newdocument fullpage | bold italic underline strikethrough | alignleft aligncenter alignright alignjustify | styleselect formatselect fontselect fontsizeselect",
toolbar2: "cut copy paste | searchreplace | bullist numlist | outdent indent blockquote | undo redo | link unlink anchor image media code | inserttime preview | forecolor backcolor",
toolbar3: "table | hr removeformat | subscript superscript | charmap emoticons | print fullscreen | ltr rtl | spellchecker | visualchars visualblocks nonbreaking template pagebreak restoredraft",
menubar: false,
toolbar_items_size: 'small',
style_formats: [
{title: 'Bold text', inline: 'b'},
{title: 'Red text', inline: 'span', styles: {color: '#ff0000'}},
{title: 'Red header', block: 'h1', styles: {color: '#ff0000'}},
{title: 'Example 1', inline: 'span', classes: 'example1'},
{title: 'Example 2', inline: 'span', classes: 'example2'},
{title: 'Table styles'},
{title: 'Table row 1', selector: 'tr', classes: 'tablerow1'}
],
templates: [
{title: 'Test template 1', content: 'Test 1'},
{title: 'Test template 2', content: 'Test 2'}
]
});</script>
</head>
<body>
<form method="post" action="somepage">
<textarea name="content" style="width:100%"></textarea>
</form>
</body>
</html>
另一方面，如果我将脚本替换为。
<script type="text/javascript" src="http://tinymce.cachefly.net/4.0/tinymce.min.js"></script>
我能完美地看到所有的图标。我已经将tinymce下载包中的所有js内容添加到了我的web项目的js文件夹中。有没有人知道这个问题的原因？
