Need help with python-mode and flake8

Hi there, I'm having trouble with python mode. Specifically, there's a command \`python-check\` which runs a code checker on the current buffer. You can specify which checker to run and by default it's \`pyflakes\`. Everything works as expected and the code gets checked. However, if I try to use \`flake8\`, the encoding is all messed up (from what I understand) and I can't seem to figure out how to fix this. You can see the code (lsp works as expected and I do get autocomplete, suggestions, documentation, etc with pyright) [All good here, lsp works as intented](https://preview.redd.it/8y7gen3xg25a1.png?width=2880&format=png&auto=webp&s=a39f3dad0a87101d23ae89d085403ebccbbc9b21) Now, if I run \`pyflakes\`, here is what I get: ​ [This is also good, pyflakes works as expected](https://preview.redd.it/jnqmsb2mh25a1.png?width=2880&format=png&auto=webp&s=0562cfde42e1713157b6c223751891fe94a50852) Now I run \`python-check\` (C-c C-v keybinding): [flake8 instead of pyflakes](https://preview.redd.it/hzx53wbuh25a1.png?width=2878&format=png&auto=webp&s=8d634256583c8f637aceeada985de442b35ee90f) And what I get is this: [flake8 encoding?](https://preview.redd.it/comv17j4i25a1.png?width=2880&format=png&auto=webp&s=e20dfd7c9e1e1544f481a4099f2f2c17a5a7211b) Which actually works, but my guess is encoding is messed up somewhere and I am not sure where exactly. As a side note, running \`flake8\` in vterm works normally: [vterm](https://preview.redd.it/eyq824ydi25a1.png?width=1446&format=png&auto=webp&s=58d7df642d53fda48f61e05390df265d133cb68a) I also tried \`(set-language-environment)\` to UTF-8, but that didn't help. Has anyone encountered something like this and resolved it? Thank you!

If I understand what you mean correctly that's not encoding, those are control characters to change color of output. They normally get interpreted by your terminal emulator. But if things are going through pipes most programs turn those colors off. I don't have a suggestion other than change your searched to look for color coding problems

Thanks! Will try. EDIT: lol, that was quick. I needed to add ansi support in compilation buffers: (require 'ansi-color) (defun colorize-compilation-buffer () (ansi-color-apply-on-region compilation-filter-start (point))) (add-hook 'compilation-filter-hook 'colorize-compilation-buffer)
