void UnicodeToGB2312(unsigned char* pOut,unsigned short uData)
{
WideCharToMultiByte(CP_ACP,NULL,&uData,1,pOut,sizeof(unsigned short),NULL,NULL);
return;
}
void Gb2312ToUnicode(unsigned short* pOut,unsigned char *gbBuffer)
{
MultiByteToWideChar(CP_ACP,MB_PRECOMPOSED,gbBuffer,2,pOut,1);
return;
}
一个简单的例子如下（随手写的一段代码，只是演示一下构造数组的过程，不要挑刺儿啊! ^_^ ）：

#include <stdio.h>
#include <windows.h>
void UnicodeToGB2312(unsigned char* pOut,unsigned short uData);
void Gb2312ToUnicode(unsigned short* pOut,unsigned char *gbBuffer);
void construct_unicode_table();
int main(int argc, char *argv[])
{
construct_unicode_table();
return 0;
}
void construct_unicode_table()
{
#define GB2312_MATRIX (94)
#define DELTA (0xA0)
#define FONT_ROW_BEGIN (16 + DELTA)
#define FONT_ROW_END (87 + DELTA)
#define FONT_COL_BEGIN (1 + DELTA)
#define FONT_COL_END (GB2312_MATRIX + DELTA)
#define FONT_TOTAL (72 * GB2312_MATRIX)
int i, j;
unsigned char chr[2];
unsigned short uni;
unsigned short data[FONT_TOTAL] = {0};
int index = 0;
unsigned short buf;
//生成unicode码表
for (i=FONT_ROW_BEGIN; i<=FONT_ROW_END; i++)
for(j=FONT_COL_BEGIN; j<=FONT_COL_END; j++)
{
chr[0] = i;
chr[1] = j;
Gb2312ToUnicode(&uni, chr);
data[index] = uni; index++;
}
//排个序，以后检索的时候就可以用binary-search了
for (i=0;i<index-1; i++)
for(j=i+1; j<index; j++)
if (data[i]>data[j])
{
buf = data[i];
data[i] = data[j];
data[j] = buf;
}
//输出到STD_OUT
printf("const unsigned short uni_table[]={\n");
for (i=0; i<index; i++)
{
uni = data[i];
UnicodeToGB2312(chr, uni);
printf(" 0x%.4X%s /* GB2312 Code: 0x%.2X%.2X ==> Row:%.2d Col:%.2d */\n",
uni,
i==index-1?" ":",",
chr[0],
chr[1],
chr[0] - DELTA,
chr[1] - DELTA
);
}
printf("};\n");
return ;
}
void UnicodeToGB2312(unsigned char* pOut,unsigned short uData)
{
WideCharToMultiByte(CP_ACP,NULL,&uData,1,pOut,sizeof(unsigned short),NULL,NULL);
return;
}
void Gb2312ToUnicode(unsigned short* pOut,unsigned char *gbBuffer)
{
MultiByteToWideChar(CP_ACP,MB_PRECOMPOSED,gbBuffer,2,pOut,1);
return;
}
用 VC 编译后，在 DOS 中执行：build_uni_table.exe > report.txt
可以得到如下的txt文件：
const unsigned short uni_table[]={
0x4E00, /* GB2312 Code: 0xD2BB ==> Row:50 Col:27 */
0x4E01, /* GB2312 Code: 0xB6A1 ==> Row:22 Col:01 */
0x4E03, /* GB2312 Code: 0xC6DF ==> Row:38 Col:63 */
0x4E07, /* GB2312 Code: 0xCDF2 ==> Row:45 Col:82 */
... ...
0x9F9F, /* GB2312 Code: 0xB9EA ==> Row:25 Col:74 */
0x9FA0, /* GB2312 Code: 0xD9DF ==> Row:57 Col:63 */
0xE810, /* GB2312 Code: 0xD7FA ==> Row:55 Col:90 */
0xE811, /* GB2312 Code: 0xD7FB ==> Row:55 Col:91 */
0xE812, /* GB2312 Code: 0xD7FC ==> Row:55 Col:92 */
0xE813, /* GB2312 Code: 0xD7FD ==> Row:55 Col:93 */
0xE814 /* GB2312 Code: 0xD7FE ==> Row:55 Col:94 */
};
然后把这个生成的数组copy到项目代码中使用就okey了。hoho，其实在开发中编写代码来构造代码的机会很多，coder不用coding辅助自己开发多浪费啊～
