To Reproduce

The dev server (in turbo mode) seems to write to a non-TTY, which is fine - I have this:

next_dev_turbo(){
  export NO_COLOR=1
  export FORCE_COLOR=0
  export TERM=dumb
  export NEXT_DISABLE_COLOR=1
  export NEXT_DISABLE_ANSI=1  # Specific to Next.js ?
  next dev --turbo
}

but I still get a bunch of colors (escape chars)

I think it's just not recognizing that's connected to a non-TTY - it really should not put out colors in that case.

Current vs. Expected behavior

The dev server (in turbo mode) seems to write to a non-TTY, which is fine - I have this:

}
