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! ^_^ ):

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~ :)
