What can we do about bugged files with Éiîéé╠ïÉæσû║ A ver101 on them?

I(the one writing this) am trying to help out my friend with an issue he is experiencing. I haven’t been able to find anything online so I thought I would ask here. My friend ask this below:

“trying to recover games and files from the catastrophe that was replacing my computer and attempting to salvage files using the apparently bugged backup however now when i try to download or run files i end up with files that have this in the name and I don’t know how to fix the issue: Éiîéé╠ïÉæσû║ A ver101

I have my region locale set to japan as the text is japanese and the japanese text has been downloaded so I’m not sure what else to do from here.”

Hello and welcome to the Glitch community.

Aside of offtopic discussion on this forum,

Neither the game that they downloaded is corrupted or something to do with localization in the computer.
