Lisp error: (wrong-type-argument utf-8-string-p "main.rs\370\210\200\200\202")

[ckruse]

Hey there,

after the last commit (82d52b0314b87b682e44fdfacc90116c8bece491), I get this error when using consult-buffer to switch buffers:

I could narrow it down to copilot-mode. When disabling it, the error disappears.

Am I doing something wrong?

Best regards, CK

[emil-vdw]

Looks like it's failing because it's encountering a non-UTF8 character in the minibuffer next to "main.rs". What does the minibuffer look like when this error would occur?

[ckruse]

It's empty.

[emil-vdw]

I will try to replicate and get to the bottom of this. For now you can disable copilot for whatever mode that minibuffer uses? Or are you using global-copilot-mode?

[ckruse]

I am using global-copilot-mode, but I can switch to an add-hook for prog-mode-hook.

Indeed that circumvents the error, nice! Thanks for the workaround!

[emil-vdw]

@ckruse I can't replicate this after installing consult and using consult-buffer. Would you mind sharing your consult config?

[ckruse]

Sorry, I was away from the computer today.

I was able to create a minimal configuration to reproduce this:

(add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/") t)
(package-initialize)

(require 'use-package)

(use-package consult
  :ensure t
  :bind
  ("C-x b" . consult-buffer))

(use-package editorconfig
  :ensure t)

(use-package s
  :ensure t)

(use-package dash
  :ensure t)

(add-to-list 'load-path (expand-file-name "copilot.el" user-emacs-directory))

(require 'copilot)

I cloned the copilot.el repository to ~/.emacs.d/copilot.el. After starting Emacs enable global-copilot-mode via M-x and then try to change the buffer: hit C-x b and then the down arrow. See this video:

https://github.com/zerolfx/copilot.el/assets/175095/8a2219be-f23a-44f1-a51e-94b57d2a60d0

This is the resulting stack trace:

Look at your stack trace and video clip, your *Minibuf-1* and *scratch* buffer names seem to have extra unknown characters. It's a placeholder in the text stack trace and character 200002 in the video (not sure though, it's blurry).

I am not sure show this is possible. Does disabling editorconfig help? Everything else seems to be just util library functions that don't modify state directly.

Yes, I did notice it.

OK, I digged down further, this character is called a „tofu“ by consult. They add (more or less) random characters to candidates to make them distinguishable. So for example two entries *scratch* would be two distinct, distinguishable candidates (see e.g. this issue).

I am not sure what to do about this, maybe it would be the best to disable copilot-mode for minibuffer-mode?

I don't think this is a problem for copilot.el. If this is a persistent problem maybe open an issue for a global copilot buffer blacklist config?
