设备控制 ASCII代码

ASCII 设备控制代码最初被设计为用来控制诸如打印机和磁带驱动器之类的硬件设备。在 HTML 文档中这些代码不会起任何作用。

HTML ISO-8859-1

HTML 4.01 支持 ISO 8859-1 (Latin-1) 字符集。

ISO-8859-1 的较低部分（从 1 到 127 之间的代码）是最初的 7 比特 ASCII。

ISO-8859-1 的较高部分（从 160 到 255 之间的代码）全都有实体名称。

这些符号中的大多数都可以在不进行实体引用的情况下使用，但是实体名称或实体编号为那些不容易通过键盘键入的符号提供了表达的方法。

注释：实体名称对大小写敏感。
