我做过GBK->Unicode的，直接根据编码对应放置相应的转换后编码才是，直接通过计算就可以定位，何苦还二分法... -gbk unicode program course

u16 gbk2uni(u8 c1,u8 c2)

{

return (c1>=0x81 && c1<=0xfe) && (c2>=0x40 && c2<=0xfe)

?

*( mb_gb2uni_table+ (c1-0x81)*0xbf+ c2-0x40 ) :

0x1fff　

}



==============================

//const u32 mb_gb2uni_size = 24066　

u16* const mb_gb2uni_table = (u16*)
