如何在网页脚本中删除\ ufeff字符？

我试图简单地说,在我的脚本中删除一个隐藏的零宽度换行字符(U + FEFF).它出现的网页是http://cynicode.co.uk(请注意,索引页面已被修改,是目前唯一正常运行的页面)

通过查看页面上的html元素,显示:

在此输入图像描述

关键点是< body >和之间的红点< !--5-- >.这种情况在盘旋时表明它是一个\ufeff角色.问题是,当我查看脚本时,没有这样的字符存在.

我使用PHP和HTML来构建此页面,以及之间的项目< !--4-- >和< !--5-- >由以下内容组成.首先,在实际的索引页面上:

<?php
  echo "<!--4-->";
  echo "<head><meta charset='utf-8' /><link rel='shortcut icon' type='image/ico' href='./images/CyniCode.ico'>
    <title>CyniCode :: Index</title>
    <meta name='description' content='The Cynic's paradise! Home of Cynical.' />
    <meta name='author' content='Cynical' />
    <meta name='keywords' content='Cynical;Blog;Code' />
    <link type='text/css' rel='stylesheet' href='./css/mystyle.css' />
    <link rel='shortcut icon' type='image/ico' href='./images/CyniCode.ico'>
    <link href='http://fonts.googleapis.com/css?family=Muli' rel='stylesheet' type='text/css' />

      m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
      })(window,document,'script','//www.google-analytics.com/analytics.js','ga');

      ga('create', 'UA-xxxxxxxx-1', 'cynicode.co.uk');
      ga('send', 'pageview'); 
    </script>

    </head>";
  require_once './functions/page.php';

这构成了索引页面.引用的page.php脚本是我的作弊,可以快速,干净地设置页面.但是......页面上的两条评论之间存在一点差异.这是两条评论之间的剩余差异.
