D3665: graph: improve graph output by using Unicode characters

[quark (Jun Wu)]

  To be clear, I have no interest in +1 or -1 this feature, and I'm not interested in spending more time testing it. I think I have made it very clear that Windows (at least WSL) is going to be a headache. Not to say, Linux (as my primary OS) font rendering is another story that might surprise you.
  
  At a low-level, the Unicode specification does not define some characters to be "wide" or "narrow" explicitly. Using them is like "undefined behavior" depending on the actual font. `encoding._wide` cannot be accurate for two reasons - 1. no way to get the font details; 2. width is per character, not a global thing.
  
  I have seen people testing software on macOS only, then think it improves everyone's life and proudly announce the feature. As a Linux/Windows user, I feel sad.
