For example, UTF-8, Cp1252.

  You know what UTF-8 is when you see it?

When we are coding we may often see some encoding specifications in our source codes such as UTF-8,GB2312. Do you know what these encoding mean and why we need them? In this post, Julián Solórzano will introduce the most widely used encoding specification around the world accomodating all different character sets in the world.UTF-8 is a method for encoding Unicode characters using 8-bit sequences. Unicode is a standard for representing a great variety of characters from many languages.Something like 40 years ago, the standard for information encoding ASCII was created. ASCII...
