How does C language display GBK Chinese characters?

dukegod

Gb2312 can be found online (below)

But gbk-encoded fonts don't work.

The offset calculated using offset = ((ch1-0x81) * 190 + (ch2-0x40)-(ch2 / 128)) * 32L is still incorrect.

What should I do?

GBK is no longer calculated by the location code like GB2312, and is directly given: high byte 0x81 ~ 0xFE, low byte 0x40 ~ 0xFE, it should be possible to place them in order. Pay attention to the endianness problem.
