G++编译时遇到错误，如何解决？

Question

问题遇到的现象和发生背景

是这样的，我今天打算用一个程序实现中文编代码，所以我将G++复制进目录来想直接调用，但发生了奇怪的错误。

运行结果及报错内容

但是，当我往程序里边拖文件并按回车后，如果文件夹包含非法字符会报错：

否则，会报错：

我的解答思路和尝试过的方法

我还把这个程序打了个包，所以这个编译程序是从快捷方式访问的。
我尝试过把路径里** 改成 **/**，但是没用。
命令粘贴到cmd中可以正常运行。
程序在特定情况下可以编译成功，例如在某些情况下直接从目录启动而非通过快捷方式。

我想要达到的结果

如果你有什么好的改进建议，请帮帮我，因为这个程序对我来说还是相当重要的。谢谢您！

程序员的常识之一：不要将程序源代码或项目或exe放在桌面这种复杂（多半带空格和汉字且在防火墙或杀毒软件严密控制的C盘上）的目录下。
