When compiled as a native application on Windows, using @fs.path_exists(directory_path)to check for a Chinese directory returns false

```moonbit
  // let directory_path = "d:/test"
  // let directory_path = "d:/测试"
  let directory_path = "d:\\测试"
  
  println("Attempting to read directory: " + directory_path)
  
  // Check if path exists first
  let exists = @fs.path_exists(directory_path)
  println("Path exists: " + exists.to_string())

```
