How to make a transliteration of files and folders when uploading to the server?

Laravel 5
Use https://github.com/barryvdh/laravel-elfinder to upload files to the server.
Need to add functionality that when uploading files to the server, producing the transliteration of Cyrillic in names of files and folders.
As I see it:
You need to override the method, which is responsible for the copy/move or send information about the file/file in subsequent handling and use, for example str_slug()
Who faced such task?
Prompt where to dig. I want to do everything correctly. Not spike.
At the moment rummage in \vendor\barryvdh
