其中解决颜色被双缓冲刷新没的方法 参考于自己的博客
用ReadConsoleOutput 解决双缓冲ReadConsoleOutputCharacterA 函数只读取字符，转义字符被过滤导致的颜色丢失问题-CSDN博客
在 wincon.h 里看到有好几个版本的 ReadConsoleOutput() WriteConsoleOutput(),于是就测试，看看能不能继续保留颜色实现双缓冲刷新，发现W 可以实现，应该是字符集宽度不同，其他的读取不到这些特殊的方格字符。
W结尾，是宽字符版本，适用于UTF-8，解决由于WriteConsoleOutput 默认窄字符，导致乱码或数据直接打印不出来。解决powshell 出不来地图的问题
WriteConsoleOutputA 也是窄字符，应该是兼容旧机器的代码。
// WriteConsoleOutput(hout, buffer, coordBufSize, coordBufCoord, &rect);
// WriteConsoleOutput(hOutBuf, buffer, coordBufSize, coordBufCoord, &rect);
// WriteConsoleOutputA(hout, buffer, coordBufSize, coordBufCoord, &rect);
// WriteConsoleOutputA(hOutBuf, buffer, coordBufSize, coordBufCoord, &rect); ReadConsoleOutputW(hout, buffer, coordBufSize, coordBufCoord, &rect); WriteConsoleOutputW(hOutBuf, buffer, coordBufSize, coordBufCoord, &rect);另外是其他提示选择在双缓冲中会被挤到最下面，因为字符缓冲区没清空。
要么增加缓冲清空代码，要么另外跑，
鄙人不大会，于是想起来旧的默认缓冲区可以试试直接清屏，于是在提示处增加了这一对代码
SetConsoleActiveScreenBuffer(hout); // 切换回原默认输出缓冲区，然后打印，因为新缓冲区清除数据麻烦，不如用旧的缓冲区，可以直接清屏/*vnsdnvlsbvhlsdvsdkj（） 等等函数被挤在这里*/
Sleep(2000);SetConsoleActiveScreenBuffer(hOutBuf); // 再换回来，继续双缓冲防止屏闪效果如图，但是发现cmd只有在编辑器里才能跑
这里换poweshell 应该是由于换了缓冲区导致键盘输入也存在不同缓冲区里了
解决方案，参考自 控制台主机不能运行，切换终端实现RPG运行-CSDN博客
