宏汇编显示中文字符

　　由于emum8088CPU支持ASCII字符集，不支持Unicode字符集，需要我们用点阵的形式显示汉字。

　　首先需要获得汉字的点阵表示形式，即16*16的表示，32个字节。

　　汉字在Unicode字符集中，由两个字节表示，前一个表示区号，后一个表示偏移地址。

　　字体库　放在了D盘目录下面：

#include <stdio.h>
int main(void)
{
    FILE* fphzk = NULL;
    errno_t err;
    int i, j, k, offset;
    int flag;
    unsigned char buffer[32];
    unsigned char word[3] = "我";
    unsigned char key[8] = {
        0x80,0x40,0x20,0x10,0x08,0x04,0x02,0x01
    };

    //fphzk = fopen("D:/hzk16k", "rb");
    err = fopen_s(&fphzk, "D:/hzk16k", "rb" );     //楷体显示的字符
    if (fphzk == NULL) {
        fprintf(stderr, "error hzk16\n");
        return 1;
    }
    offset = (94 * (unsigned int)(word[0] - 0xa0 - 1) + (word[1] - 0xa0 - 1)) * 32;
    fseek(fphzk, offset, SEEK_SET);
    fread(buffer, 1, 32, fphzk);
    for (k = 0; k < 32; k++) {
        printf("%02X ", buffer[k]);
    }
    for (k = 0; k < 16; k++) {
        for (j = 0; j < 2; j++) {
            for (i = 0; i < 8; i++) {
                flag = buffer[k * 2 + j] & key[i];
                printf("%s", flag ? "●" : "○");
            }
        }
        printf("\n");
    }
    fclose(fphzk);
    fphzk = NULL;
    return 0;
}

　　　　如上图，获得了汉字 “我”的点阵表达形式。

”我的计算机工作正常“  点阵表示：
