I know because i have installed the server on a new windows 10 computer.

Try changing your codepage by running chcp 850 first.

Why do you need the FiveM server to work on Windows 8.1 anyway?

first : thx for your answer and because my server is on my computer and my computer is on "windows 8.1" and i'm sorry but what is "chcp 850" and how can i run that before ?

You run it before starting you server. Please, this is not a support platform. I've told you multiple times to use the forums now.
