//：全角Dbd转半角Cbd
(*
//半角全角互转原理：：：
1、在windows和POSIX中,采用TEncoding.GetEncoding('GB2312')时：
中文和全角字符都占两个字节：
ASC编码：范围：0~255，共256个字符
！！ASC编码：asci chart 1 (codes 33 - 126 )：可见且可打印的字符
ASC编码：ascii chart 2 (codes 127 - 255 )：不可见且不可打印的控制符
！！其中：32位空格:可见且 非 打印字符
：33-126：为可见且 可 打印字符
！！全角空格:第1个字节 和 第2个字节 均为161。：
！！全角字符（除全角空格）的第1个字节总是被置为163，
而第2个字节则是 相同半角字符码加上128（不包括空格）
如半角a为65，则全角a：则是163（第1个字节）、 193 （第2个字节， 128 + 65 ）。
！！中文来讲，它的第一个字节被置为大于163，（
如 ' 阿 ' 为: 176 162 ）,我们可以在检测到中文时不进行转换。
2、在windows和POSIX中,采用TEncoding.Unicode时【最标准国际化的用法】
//非全角空格的全角字符（【句号】无全角，逗号有全角）：判断条件第2个字节=255，输出：其半角字节=第1个字节+32
//全角特例：
//2.1、全角空格：判断条件第2个字节=48而第1个字节0，输出：其半角字节=32
//2.2、全角逗号：判断条件第2个字节=48而第1个字节2，输出：其半角字节=46
//半角字符：判断条件第2个字节=0，输出：其半角字节=第1个字节
//中文：判断条件第2个字节<>0 and 48 and 255，输出：就是它本身
