 * ver 1.7 2005-07-26
 * 修改了while循环导致的bug。此bug当字符串最后一个字符为"0"的时候将处理错误。
 * 受影响方法: CHStoUTF8() , CHStoUNICODE()
 * (by Zeal Li ,http://www.zeali.net/)
 *
 * ver 1.6 2005-05-16
 * 构造函数增加了一个参数以便用户可以方便的在使用的时候设置配置文件路径
 * (by Zeal Li ,http://www.zeali.net/)
 *
 * ver 1.5 2003-06-06
 * 增加 UTF8 转换到 GB2312、BIG5的功能。
 *
 * ver 1.4 2003-04-07
 * 增加 当转换HTML时设定为true,即可改变charset的值。
 *
 * ver 1.3 2003-04-02
 * 增加 繁体中文转换至拼音的功能。
 *
 * ver 1.2 2003-04-02
 * 合并 简体、繁体中文转换至UTF8的函数。
 * 修改 简体中文转换至拼音的函数,返回值更改为字符串,每一个汉字的拼音用空格分开
 * 增加 简体中文转换为 UNICODE 的功能。
 * 增加 繁体中文转换为 UNICODE 的功能。
 *
 * ver 1.1 2003-04-02
 * 增加 OpenFile() 函数,支持打开本地文件和远程文件。
 * 增加 简体中文转换为 UTF8 的功能。
 * 增加 繁体中文转换为 UTF8 的功能。
 *
 * ver 1.0 2003-04-01
 * 一个集合了中文简体,中文繁体对应各种编码互换的类库已经初步完成。
