How to use command prompt to delete file with special characters?

Question

I found this answer on Server Fault, but it is nearly 10 years old and doesn't work anyway

I have files with names like:

AlchBagSquare_Black°.nif
League-of-Legends-фэндомы-1759411.jpeg

When I attempt to use del {filename} to delete them, it just says:

Could Not Find {filename}

I need a single, comprehensive solution that will work for all special characters via the Windows 7 command line.

Edit: I am generating a batch file to delete files, so it also cannot require user input.

Edit 2: Here's how I am using the delete command:

del /F "D:\backup\League-of-Legends-фэндомы-1759411.jpeg"

Answer 1

None of your characters are invalid like the other question (which uses the forbidden : in the name)

So what you need to do is using Unicode by saving the batch file as UTF-8 without BOM and changing the codepage to UTF-8 (65001) if it's not the default

chcp 65001
del AlchBagSquare_Black°.nif
del League-of-Legends-фэндомы-1759411.jpeg
