说明：  构建 GB2312 汉字库的 unicode 码表嵌入式系统总离不了处理汉字。一般汉字的处理方法是（以手机接受短信为例）：比如你收到了一封短信，该短信解码后是按照 UTF-16 表示的，那么我们需要根据每一个汉字的unicode 码找到它在 GB2312 库中的位置，然后再用对应的点阵数据在屏幕上显示出来。
(GB2312 Store Construction of unicode code table from the total embedded system can handle Chinese characters. Ordinary Chinese method of disposal is (to accept phone messages for example) : For example, you received an SMS, after decoding the messages is UTF-16 said, we need every one of the Chinese characters unicode code found in GB2312 repository location, Then the corresponding lattice data on the screen is displayed.)
