特殊字符Unicode Entity Codes表
原文地址：http://lightgis.com/2010/Unicode-Entity-Codes-can-be-used-by-csharp.html
被上标给折腾的 只是想给计算出的面积加上平方的上标 可惜不知道 还楞是搜不到 最后想这些特殊字符的核心code应该是一样的吧 就用html里的平方上标code换成C#的转义字符 居然成了 囧··· 时间大把流逝···
具体是这么用这个表的：
比如想显示∞（根号无穷）
在表中找到∞ 及其HexEntity
∞ （HTML中可以直接用）
在C#中需要用转义符 即/x221E
再比如在C#中表示平方上标 即用/x00b2

Fractions
These codes display fractions set to be all within one line with smaller number, but they can be replaced by other ways of typing a fraction (e.g. "1/2").
-- means no HTML entity code exists and that a numeric code must be used.

X-Bar, P-Hat and D-Bar
Some codes like that for x̄ (X-bar) are actually a combination of two codes - the base letter x plus a code for the line above (̄: or ̄). Capital letter may need to be reduced in size to accomodate the placement of the combining diacritic.
Note on Safari: These symbols use combining characters and may not be correctly Safari 2 or other older browsers.
