Encoding

Basically, our "Hello, Makers" is a string. String is a collection of chars. If we take a deeper understanding about char in C#, we could see an UTF-16 code unit, a unicode character encoding format.

Encoding needs because computer can't read char or string, computer can only read 1 or 0. That's why we need an encoding to convert the string to 1 or 0.

Search in google for 'H' unicode. It is U+0048.

Open interactive visual studio console. It is located on View > Other windows > C# interactive. Check our encoding type.

> char capitalH = '\u0048';
> capitalH
> 'H'
