Output special chars

[chalmagean]

How can I get rid of those special characters in my error output?

[Bogdanp]

Most of those escape sequences (except for ^[[36m) should be taken care of elm-compile--colorize-compilation-buffer. Try requiring ansi-color before you initialize elm-mode and make sure elm-compile--colorize-compilation-buffer is in your compilation-filter-hooks.

That doesn't seem to work. I still get those characters.

Then you might have a different hook in compilation-filter-hooks (before the colorize hook) that's interfering or it could be due to something else in your setup. This seems to work fine on a vanilla Emacs install so I'm closing this issue for now.
