HTML Unicode问题：如何显示特殊字符
[英]HTML Unicode Issue: How to display special characters
问题描述
Currently, I have my webpage set to Unicode/UTF-8. 
目前，我的网页设置为Unicode / UTF-8。 When trying to display a special character (for example, em dash, double arrow, etc), it shows up as a question mark symbol. 当试图显示特殊字符（例如，短划线，双箭头等）时，它会显示为问号符号。 I cannot change these characters to the HTML entity equivalent. 我无法将这些字符更改为等效的HTML实体。 How can I circumvent this issue? 我该如何规避这个问题？

A question mark in a lozenge, , indicates a character-level error: the data contains bytes that do no represent any character, according to the character encoding being applied. 菱形中的问号 表示字符级错误：根据所应用的字符编码，数据包含不代表任何字符的字节。 This typically happens when the document is declared as UTF-8 encoded but is really in iso-8859-1, windows-1252, or some similar encoding. 这通常发生在文档被声明为UTF-8编码时，但实际上是在iso-8859-1，windows-1252或类似的编码中。 Windows-1252 is a common default encoding used by various programs on Windows platforms. Windows-1252是Windows平台上各种程序使用的常见默认编码。 So you may need to open the file in your authoring program and re-save it as UTF-8 encoded. 因此，您可能需要在创作程序中打开该文件并将其重新保存为UTF-8编码。
If problems remain, please post the URL. 如果问题仍然存在，请发布网址。 Posting the code alone is not sufficient, since the character encoding is primarily specified in HTTP headers. 单独发布代码是不够的，因为字符编码主要在HTTP头中指定。
If you see a question mark in a small box, then it might be a font-level problem (lack of glyph in the fonts being used), but this would be very rare for common characters like the em dash. 如果你在一个小方框中看到一个问号，那么它可能是一个字体级问题（正在使用的字体中缺少字形），但对于像em破折号这样的常见字符来说这是非常罕见的。 Different browsers have different ways of indicating character- or font-level problems. 不同的浏览器有不同的方式来指示字符或字体级别的问题。

Make sure your document is set to the correct character encoding in the actual code editor, as well as in the doctype. 确保在实际代码编辑器和doctype中将文档设置为正确的字符编码。 Both are necessary. 两者都是必要的。 I spent hours trying to tweak HTML when the only problem was that I needed to set the text setting in Coda. 当我唯一的问题是我需要在Coda中设置文本设置时，我花了几个小时试图调整HTML。

Make sure your characters are actually UTF-8 characters. 确保您的角色实际上是UTF-8字符。 They will probably look something like this: 他们可能看起来像这样：
