I've tried to reinstall/reinstall and clean every version of ruby with no success. I use Ruby 2.3.3 and rails 5.1.4. Thanks

@Salil Thanks for your answer but it still throw the same error. — Léo Coletta, Dec 08 '17 at 08:27
Make sure you are not pasting non-UTF-8 chars into console. Just type `rails c` 7 check. also ref :- https://github.com/ConnorAtherton/rb-readline/issues/139 — Salil, Dec 08 '17 at 08:32

Since you are on Windows(I'm assuming since you have D:/):

Try installing rb-readline gem in your development group. That's the easiest way for solving readline issues.

There are other solutions as well if that doesn't work.
