@ghord Do you want any characters to be supported? or do you have any rule? Many languages - C#, Java, Go, Python, Elixir, etc. - support Unicode identifiers as defined...

@ghord Yes but... Relaxation is not necessarily good. For instance, the following code is valid in Swift. I personally don't like this identifier rule. ```swift import Foundation var ⁡ =...

IMO, C# should follow [Unicode® Standard Annex #31](http://unicode.org/reports/tr31/). From this stand point, `var 𝟎 = 2` is disallowed but `var a𝟎 = 2` should be allowed. Roslyn violates C# specification....

If `value` is a keyword, how is `nameof(value)` handled? ```cs public int X { set { var n1 = nameof(value); // no error var n2 = nameof(this); // CS8081 var...
