短信发送(M800)

在实习的时候，做了一个关于发送短信的接口，营运商提供一个url，且信息如有中文字符的，必须用 DCS 8的格式，当时懵了。。DSC是什么鬼。。后来百度了一大堆资料DSC 8就是用UCS格式做的和咨询M800公司的工程师，才得以解决。。。在编译文字这里花费了好长的时间。大概了解UTF-8 与UCS2的网站有http://www.52rd.com/Blog/Detail_RD.Blog_thieven_4865.html。基层的基本不写了。底层的转换源码如下：

代码：

package com.sms.utils.sendMsg.m800;

import java.io.UnsupportedEncodingException;
import java.net.URLDecoder;
import java.net.URLEncoder;
