Issue:
Display is broken on some platforms
Hi,

Yesterday I was playing with [Gleam](https://github.com/gleam-lang) and noticed that the errors displayed in my terminal (Cmder on Windows 10) are kinda broken.

It looks like this :
![image](https://user-images.githubusercontent.com/1208646/105060112-4b401b80-5a78-11eb-8382-749367191bd9.png)

I guess it would be hard to have something that works on all platforms if it uses "advanced characters" (especially  on Windows). I think, it would be easier to run correctly on all platforms if diags could be displayed using only ASCII characters (ie whose range are in 0-127). I see many possible solution. One could be using an enum to instantiate a ``Char`` struct in Legacy (only ASCII) or Standard mode (make advantage of UTF-8 and Unicode) . Another one could be using cfg expression for the default value where it would change based on the platform it is compiled for. The one thing I don't know how to solve is by what should be replacing the characters that are troublesome. Especially for corners, they are single character for now and there isn't a look alike character in pure ASCII. More than one character could be used then but it would offset alignment. 

For the record, rustc seems to be only using ASCII chars.

Pull request:
rendering in US-ASCII only
