Python脚本，用于将网络摄像头图像转换为cmd中的ASCII，而不会打印unicode

Question

我发现这个python脚本可以将网络摄像头的输入转换成ASCII格式，并在命令行中进行了一些修改以满足我的需要。我想在输出中添加一个Unicode字符，但它目前只打印出一个框，而不是在我实际运行时打印出正确的Unicode字符。我需要更改什么以确保它打印出实际的Unicode字符？你知道吗

这取决于您使用的终端仿真器。emoji字符在终端中显示为方框的原因是终端仿真器不支持Unicode字符。你知道吗

我刚刚在iTerm2上测试了您的代码，它支持Unicode，并且可以正常工作。你知道吗
