在网页中显示数学符号
在网页中显示一些符号，如数学符号(Insus.NET仅提供常用符号)：
前提条件是你的网页是支持utf-8，如在web.config设置如下：
View Code
<configuration>
<system.web>
<globalization fileEncoding="utf-8" requestEncoding="utf-8" responseEncoding="utf-8" />
</system.web>
</configuration>
<system.web>
<globalization fileEncoding="utf-8" requestEncoding="utf-8" responseEncoding="utf-8" />
</system.web>
</configuration>
