Why is  appearing in my HTML?

I see this character in Firebug .
我在 Firebug 中看到了这个角色。
I don't know why this is happening, there's no such character in my code. For Firefox it's OK, but in IE everything breaks. I can't even search for this character in Google.
我不知道为什么会这样，我的代码中没有这样的字符。对于 Firefox 来说没问题，但在 IE 中一切都中断了。我什至无法在 Google 中搜索此字符。
I saved my file with utf-8 encoding without bom.
我用没有 bom 的 utf-8 编码保存了我的文件。
回答by RHSeeger
The character in question is the Unicode Character 'ZERO WIDTH NO-BREAK SPACE' (U+FEFF). It may be that you copied it into your code via a copy/paste without realizing it. The fact that it's not visible makes it hard to tell if you're using an editor that displays actual unicode characters.
有问题的字符是 Unicode 字符“零宽度无间断空间”（U+FEFF）。可能是您在没有意识到的情况下通过复制/粘贴将其复制到您的代码中。它不可见的事实使得很难判断您是否正在使用显示实际 unicode 字符的编辑器。
One option is to open the file in a very basic text editor that doesn't understand unicode, or one that understands it but has the ability to display any non-ascii characters using their actual codes.
一种选择是在不理解 unicode 的非常基本的文本编辑器中打开文件，或者在理解它但能够使用其实际代码显示任何非 ascii 字符的文本编辑器中打开文件。
Once you locate it, you can delete the small block of text around it and retype that text manually.
找到它后，您可以删除它周围的小块文本并手动重新键入该文本。

Just use notepad ++ with encoding UTF-8 without BOM.
只需使用记事本 ++ 编码 UTF-8，无需 BOM。

yeah, its so simple to fix that, just open that file by notepad++ and step follow --> Encoding\ encoding UTF-8 without BOM. then save that. It work for me as well!
是的，解决这个问题很简单，只需通过记事本++打开该文件，然后执行步骤 --> Encoding\ encoding UTF-8 without BOM。然后保存。它也适用于我！

Try:
尝试：
<?php
// Tell me the root folder path.
// You can also try this one
// $HOME = $_SERVER["DOCUMENT_ROOT"];
// Or this
// dirname(__FILE__)
$HOME = dirname(__FILE__);
// Is this a Windows host ? If it is, change this line to $WIN = 1;
$WIN = 0;
// That's all I need
?>

"I don't know why this is happening"
“我不知道为什么会这样”
Well I have just run into a possible cause:-) Your HTML page is being assembled from separate files. Perhaps you have files which only contain the body or banner portion of your final page. Those files contain a BOM (0xFEFF) marker. Then as part of the merge process you are running HTML tidy or xmllint over the final merged HTML file.
好吧，我刚刚遇到了一个可能的原因:-) 您的 HTML 页面是由不同的文件组合而成的。也许您的文件只包含最终页面的正文或横幅部分。这些文件包含一个 BOM (0xFEFF) 标记。然后作为合并过程的一部分，您将在最终合并的 HTML 文件上运行 HTML tidy 或 xmllint。
That will cause it!
那会造成的！

If you are using Notepad++, "Menu" >> "Encoding" >> "Convert to UTF-8" your "include" files.
如果您使用 Notepad++，“菜单”>>“编码”>>“转换为 UTF-8”您的“包含”文件。

An old stupid trick that works in this case... paste code from your editor to ms notepad, then viceversa, and evil character will disappears ! I take inspiration from wyisyg/msword copypaste problem. Notepad++ utf-8 w/out BOM works as well.
在这种情况下有效的一个古老的愚蠢技巧......将代码从您的编辑器粘贴到 ms 记事本，然后反之亦然，邪恶的角色将消失！我从 wyisyg/msword 复制粘贴问题中获得灵感。Notepad++ utf-8 w/out BOM 也能工作。
回答by kurdtpage
Here's my 2 cents: I had the same problem and I tried using Notepad++ to convert to UTF-8 no BOM, and also the old "copy to MS notepad then back again" trick, all to no avail. My problem was solved by making sure all files (and 'included' files) were the same file system; I had some files that were Windows format and some that had been copied off a remote Linux server, so were in UNIX format.
这是我的 2 美分：我遇到了同样的问题，我尝试使用 Notepad++ 转换为无 BOM 的 UTF-8，以及旧的“复制到 MS 记事本然后再返回”技巧，但都无济于事。我的问题是通过确保所有文件（和“包含”文件）都是相同的文件系统来解决的；我有一些是 Windows 格式的文件，还有一些是从远程 Linux 服务器复制的，所以是 UNIX 格式。
