What is "Character" in lua?

I'm still wondering what "Character" means.. Can somebody explain to me?

In the context of ROBLOX Lua, "character" has two meanings.

1) It is the model that the player appears in physically (the character model) containing your equipped tool, hats, and torso, head, legs, and arms. It is a property of a Player and can also be reverse-looked-up using (GetPlayerFromCharacter)[http://wiki.roblox.com/index.php?title=GetPlayerFromCharacter_(Method)].

2) It is the smallest component of a string. For instance, "#" is a single character, or "a" is a single character, or "." is a single character. Strings can be interpreted as lists of characters.

Ex.: "the cat" is a string consisting of 7 characters, 6 of them unique. "The cat" is a string consisting of 7 characters, all 7 unique. The fourth character of "model" is "e".

It's a Model of ur Player
