A way of writing a line in a specific font [C# Console]

Alright I basically want to write a specific line in a different font, example:

Console.WriteLine("Line with regular font");
Console.WriteLine("Line with a special font");
Console.WriteLine("Line with regular font");
Console.WriteLine("Line with regular font");

Hope you get what I'm saying, and of course on a console app.

I already know this method: Console.OutputEncoding =

But that would change the whole console font, and I need a specific line

Console.OutputEncoding has nothing to do with fonts. It's encoding, like ASCII or UTF-8. You cannot do that because a console doesn't deal with fonts. It's just a stream of characters.

If you want to be change the font on a line by line basis you need to make your own GUI application to display the lines of text in the window.

Only by using kernel api, don't forget to enable unsafe code in Project Properties>Build>Allow Unsafe Code
