So first, I tried it in Visual Studio 2010, silently hoping that the troubles are gone. And yes, the extra boldness of some symbols is no more the case. Here is how it looks:

After that I switched to Visual Studio 2012. No surprises, the font is rendered perfectly:

So I guess, the confrontation is over. If you love Inconsolata font, just get its latest version from google code repository and enjoy!
