到目前为止，我们编写的C 程序，其用于人机交互的提示或菜单都是英文
的，那么如何在没有汉化的Turbo C 集成开发环境下编制显示汉字的程序呢？
解决这一编程问题，我们首先必须了解有关汉字编码及字库的知识。根据对汉字使
用频率的研究，可把汉字分成高频字(约100 个)，常用字(约3000 个)，次常用字(约4000 个)，
罕见字(约8000 个)和死字(约45000 个)，即正常使用的汉字达15000 个。我国1981 年公布
了《通讯用汉字字符集(基本集)及其交换码标准》GB2312-80 方案，把高频字、常用字、和
次常用字集合成汉字基本字符集(共6763 个)，在该集中按汉字使用的频度，又将其分为一
级汉字3755 个(按拼音排序)、二级汉字3008 个(按部首排序)，再加上西文字母、数字、图
形符号等700 个。
汉字编码:
区位码
国家标准的汉字字符集(GB2312—80)在汉字 *** 作系统中是以汉字库的形式提供的。汉
字库结构作了统一规定，即将字库分成94 个区，每个区有94 个汉字(以
位作区别)每一个汉字在汉字库中有确定的区和位编号(用两个字节)，这就是所谓的区位码
(区位码的第一个字节表示区号，第二个字节表示位号，因而只要知道了区位码，就可知道
该汉字在字库中的地址，每个汉字在字库中是以点阵字模形式存储的，如一般采用16×16
点阵形式，每个点用一个二进位表示，存1 的点，当显示时，可以在屏上显示一个亮点，存
0 的点，则在屏上不显示，这样把存某字的16×16 点阵信息直接用来在显示器上按上述原
则显示，则将出现对应的汉字。
内码
汉字使用两字节表示，国家制定了统一标准，称为国标码。国标码规定，每个字节使用
后面7 位，第一位为0。为了区别于英文的ASCII 码，国标码在计算机上使用的时候，规定
汉字每个字节第一位设置为1，以表示该两字节为汉字，称为内码。以“大”字为例子：
国标码3473H： 0 0 1 1 0 1 0 0 0 1 1 1 0 0 1 1
内码B4F3H： 1 0 1 1 0 1 0 0 1 1 1 1 0 0 1 1
国标码与内码有一定的转换公式，即16 进制的区位码，两个字节各加80H，就成为了
国标码。
汉字字模在字库中存放的位置根据汉字的区位码来确定，内码是汉字在机内的表示。由
于区位码和内码存在固定的转换关系，所以当在支持汉字输入的系统中，键盘输入的汉字内
码即在程序中存在，将其转换为区位码，再从字库中找到对应的汉字字模，然后再用有关的
位 *** 作和循环语句，对每个字节的每一位进行判断，如同过滤一样，如果某位是1，则按设
置的颜色在屏幕的相应位置画点（用graphicsh 中的显示象素点的函数putpixel()），若某位
为0，则不画点，这样就可按预先设置的颜色在相应位置显示出该汉字来。
内码到区位码的转换
若汉字内码为十六进制数h2h1l2l1，则区号qh 相位号wh 分别为：
qh= h2h1-0xa0;
wh= l2l1-0xa0；
若用十进制表示内码为dld2，则
qh=dl-l60；
wh=d2-160；
即区位码qw 为：
qw=100(d1-160)十(d2-160);
反过来，若已经知道了区位码qw。则也可求得区号和位号：
qh=qw/100；
wh=qw-100qh;
因而该汉字在汉字库中离起点的偏移位置(以字节为单位)，可计算为：
offset=(94(qh-1)+(wh-1)) 32;
注意：字库中每1 区有94 个字符。
这样，就可以找寻到文件的偏移量，读出一个char bytes[32]数组。这样bytes 数组中则
存了要显示汉字的16×16 点阵字模，然后将字模按行扫描的办法，通过循环用putpixel()函
数在屏幕设定位置显示出象点，因而组合成一个显示的汉字。
这个会压小。看大图到这看

我也不怎么会，还在学习中
下面有一个1616的C程序
参考一下。。。

取负得正。
程序与硬件电路反了。解决方式最好的方式是改字模。字模就是反着取。字就正了。改程序，改电路。
程序是按行来处理的，每行是16个点阵，需要2个字节来存储，根据程序表达的意思，点阵表也是按行来建立的，而每次取数只能一个字节，所以i这个行号需要乘以2，ia是每行的字节位置，取值范围为12。
