When I call gcalcli from the bash shell, I get the output described in the documentation. But when I run M-x shell on emacs (24.3) and call gcalcli from there, I get a lot of ^[ characters. Compare screenshots from the shell and from emacs.
My init.el already contains the following lines, which are supposed to help with this.
(add-hook 'comint-output-filter-functions
'comint-output-ctrl-m)
I don't really have a problem with calling gcalcli from the shell whenever I need it. I just want to understand why emacs uses non-printing characters here and how to suppress them if I want to.
