I am using Windows 10 as my operating system. Whenever I duplicate a file or folder to the same location, Windows automatically adds the word “copy” to the end of the file name, which is a useful feature. However, I have noticed that there is a strange occurrence where two invisible characters are added to the beginning of the file name.

To investigate this further, I copied these characters to a binary editor and discovered that their codes were U+200F. The name of the character is “RIGHT-TO-LEFT MARK” and its binary representation is e2 80 8f.

I am now wondering what steps I can take to remove this odd behavior. For context, my operating system is Microsoft Windows, version 10.0.17134.885.
