HTML字符实体引用Character Entity References in HTML 4 and XHTML 1.0

HTML实体常用于生成那些键盘上没有的印刷字符，比如€、∞、≠、©等等。

HTML实体以和号（&）开头，分号（;）结尾，两者之间表示实体的字符串（或数字）。

这里摘抄了国外一个比较完整的HTML实体表格作为个人的备忘，并分享给大家。

每个表有五列。

第一列包含实体引用，是常用的&entity_name;形式。

第二列显示该实体出现在浏览器的效果。

第三列包含实体引用，是&#number;形式。

第四列显示该实体出现在浏览器的效果。

第五列是实体的描述。
