Just added this to my doom emacs and am getting ANSI escape sequences in the comint output:

�7<0>                                                                                                                                                                                       | order: Forth Forth Root     Forth �8

in particular: ^[7 and ^[8. My install is just straight forward use-package (but hooked into Doom's package system):

(use-package! forth-mode
  :defer t
  :config

  (set-repl-handler! 'forth-mode 'forth-mode-switch-to-output-buffer)

  (set-lookup-handlers! 'forth-mode
    :documentation #'forth-spec-lookup-2012)

  (setq forth-executable "gforth")

  (map! :after forth-mode
        :map forth-mode-map
        :localleader
        "," #'run-forth
        "." #'forth-eval-last-expression-display-output
        "u" #'forth-eval-last-expression
        "'" #'forth-load-file
        "r" #'forth-eval-region
        "s" #'forth-see
        "S" #'forth-switch-to-output-buffer
        "e" #'forth-eval-defun
        "R" #'forth-restart
        "H" #'forth-spec-lookup-1994
        "h" #'forth-spec-lookup-2012
        ))

From reading the source I would have expected forth-scrub to filter these out but that doesn't seem to be the case. I do use:

(add-to-list 'comint-output-filter-functions 'ansi-color-process-output)

to process the sequences for other modes but this does not work for forth-interactive-mode

Thanks for the bug report. Unfortunately I'm busy with other things, so I don't have time to look into this now.
