*Python Check* buffer showing weird characters

[djzurawski]

Summary

Just installed Emacs 29.1. When elpy-check finds problems the buffer that opens contains weird characters (I think something to do with coloring that isnt working). I dont know if this an Emacs issue, elpy issue, or elpy interacting with Emacs issue.

Here's an example

Those are color codes. Looks like your compilation buffer isn't setup to interpret those so it just prints them out. Google around to either:

A) Strip them out entirely if you don't care about coloring B) Make it so that it will color the buffer.

Closing since this is not elpy issue. Please re-open if this is not the case
