What's the Leet Speak?

Leet (or 1337 or l33t5p34k) is a language developed with the advent of the Internet, composed of ASCII characters graphically similar to the usual alphanumeric characters.

The term leet speak comes from elite speak which oppose those who do not understand the language, the neophytes (noobs).

How to write using Leet Speak?

The Leet Speak language consists of replacing the common characters (letters A-Z and sometimes digits 0-9) by others having a similar writing. The leet writing is therefore not unique and there are more or less complex variants for each character.

In its most basic version, the leet replaces at least the letter E by the number 3, the letter O by the number 0, the letters I and L by the number 1, the letter S by the number 5 and the letter T by the number 7.

Example: LEET therefore translates to 1337
