We don't use them in my project, I only added an exception for ©®™ and such. You can easily whitelist any character range you need. My command looks like this:

- (! grep -r -I -P '[^\x{00}-\x{7f}©®™°]' src)

They add excessive logging too. I had cursor write some UI code and I thought my console was going to explode. Console logs each step of the way haha. I guess that's the easiest way for it to debug its own code
