html中显示特殊符号（附带特殊字符对应表）

问题重现

在使用html进行编辑的时候，特殊符号往往会显示错误，极端情况下更可能导致网页崩溃。如下面这段代码：

<table>
<tr>
<td>
中_国_人
</td>
</tr>
</table>

1
2
3
4
5
6
7

在网页中则显示为：

html中显示特殊符号（附带特殊字符对应表）-风君子博客

这里将两个下划线自动转化为斜体标识符，导致输出结果有误。

解决方法

这里建议使用字符编码来替换掉原特殊字符，如将上述代码改为：

<table>
<tr>
<td>
中``` |```&#95;``` |国``` |```_``` |人
</td>
</tr>
</table>

1
2
3
4
5
6
7

则输出变为：

html中显示特殊符号（附带特殊字符对应表）-风君子博客
