Solution 1

If this code compiles on 2012 and 2013 (I doubt that), than it is a bug...
According to C# specification such a sign can not be part of of a variable name (see 2.4.2 Identifiers)...
For sure it does not compile in 2008/2010/2015...

Solution 2

Just to complete what Peter says: that code doesn't compile under VS2013 either:

C#

Error	1	Unexpected character '●'

It's not a legal character in variable names in C# of whatever vintage.

The example doesn't in my version of VS20013 - I get the error you see above.
The dropbox version I can't check - I have no way to type in those characters.

Hi Sir, public const string バー·ー = "0";

public const string バーー = "0"; has no error, but if there is · error now occurs...

I copy both lines into VS2013.
I get an error on the first one, and noth on the second.
You cannot use that character in variable names, not in VS2010, VS2013, VS2015, ...
It is not a valid character!

Hi Sir, I tried this..

Works in VS 2005/2012.. (I set the Encoding in VS2005 to Unicode - CodePage 1200)
public const string バー・ = "0";

Errors in VS2015:
public const string バー・ = "0";
