Thanks for the all comments.

I got to know how to solve this, but I don't know why.

This commands make it work:

(setq process-coding-system-alist (cons '("bash" . (utf-8-nfd . utf-8-nfd)) 
process-coding-system-alist))

Do you know what the "utf-8-nfd" means there? utf-8 or utf-8-unix does not work.
