The dots aren't everywhere:
version atom :
••••channel = chat_message.channel
version sublime :
I use this dots for indent. But i use them for non-breaking space too.
I would like to detect the non breaking point easily. Like a warning "you are doing a mystake dude ! ". "Thx Atom you rox ! "
If I copy/paste a text and there is a non-breaking space in it, the point won't be print like normal space.
But maybe you have another solution like non-breaking space have a red background.
