But it's the same font on both systtems. I started emacs with the 
following args to reproduce the bug and take the screenshots :
#+begin_src sh
emacs -q --no-site-file --no-site-lisp --no-splash -fn "-*-DejaVu 
Sans Mono-normal-r-*-*-12-*-*-*-c-*-iso8859-1"
#+end src

And even if you suppress the (setq ...) which define the character 
the result is still the same :
a thin line on Gnu/Linux an wider one on Windows.
