Ncurses在光标后显示不需要的文本

我昨天问了一个问题，你们帮了我很大的忙。之后又出现了另一个问题，这次是关于ncurses的。每当我移动箭头（时，您的终端定义似乎是正确的，因为

[B

是CygWin的光标向下转义序列，在运行代码时，它确实移动了光标

然而，这些转义序列也出现了，这意味着它们来自某个地方，结果表明它们来自于方程的输入端，而不是输出端

---

当你按下向下箭头时，转义序列首先会回显到屏幕上，然后对输入进行操作，在输出

之前将光标移动到正确的位置，我明白了，所以这是Cygwin的错。是有什么办法让终端识别它，还是我只需要使用不同的终端？@Vishnu，做了更多的调查，原来我最初的猜测是错误的。请参阅更新。非常感谢您花时间查看。这确实是答案！
