What value do you get if you evaluate the following expression:

   (process-coding-system (get-process "shell"))

You can do the evaluation with M-:

Since you are using the Cygwin bash, you need to use undecided-unix
(or something -unix, anyway) in the cdr of the cons cell that is
returned by process-coding-system.  You can probably use
set-process-coding-system to change the defaults.

(Btw, if your Emacs is a native Windows build, then you should expect
these surprises, because native Windows programs and Cygwin programs
are subtly incompatible, the matters related to EOL format being one
of the aspects of this incompatibility.  Why not use the Cygwin build
of Emacs instead?)

Encoding and decoding works below the Lisp level.
