HTML5中的字符实体
HTML5中保留了一些字符。 例如，您不能在文本中使用大于或小于符号或尖括号，因为浏览器可能会将它们误认为是标记。
HTML5处理器必须支持下表中列出的五个特殊字符。
| 符号 | 描述 | 实体名称 | 数字代码 |
|---|---|---|---|
| " | quotation mark | " | " |
| ' | apostrophe | ' | ' |
| & | ampersand | & | & |
| < | less-than | < | < |
| > | greater-than | > | > |
要将一个元素和属性写入您的页面，以便代码向用户显示而不是由浏览器处理（例如，作为
），您可以写 -&div id="character">
HTML5感知处理器应该支持一长串特殊字符。 为了使这些文档出现在您的文档中，您可以使用数字代码或实体名称。 例如，要插入版权符号，您可以使用以下任一项 -
© 2007
or
© 2007
ISO 8859-1字符集是最广泛使用的字符集。 ISO 885901字符集的完整参考如下。
