What is the difference between C# and Node.js Console output?

Question

I'm using the Console API from C# and find a difference between the Console API from Node.js when try to use console commands to change color (`\x1B[31m'):

Using Node.js this code:

 console.log("\x1B[31mTeste");

Prints this:

When I use this C# code:

Console.Write("\x1B[31mTeste");

I get this output:

Why have this difference?

yes, I know that x1B[31m is a code for terminal change color.. I just don't understand why c# don't work with this. (I will edit my question to make this more clear) — thur, Sep 06 '17 at 03:21

I know.... but node emulates a console, so you need something to do the same from Console.Write .... — Keith Nicholas, Sep 06 '17 at 03:42

Node uses https://github.com/libuv/libuv to emulate an ANSI console. The normal windows console doesn't support this, therefore trying to do it from C# won't work.

The console in Windows 10 supports virtual terminal sequences, but it has to be enabled first via WinAPI `GetConsoleMode` and `SetConsoleMode`. In older versions you can use ANSICON or ConEmu, which use DLL injection to hook WinAPI console functions such as `WriteConsole`. – Eryk Sun Sep 06 '17 at 06:58
