Furthermore, what does UTF 8 encoding mean?

UTF-8 is a compromise character encoding that can be as compact as ASCII (if the file is just plain English text) but can also contain any unicode characters (with some increase in file size). UTF stands for Unicode Transformation Format. The '8' means it uses 8-bit blocks to represent a character.

Beside above, why is utf8 important? Most importantly, UTF-8 supports just about every character in every language you can think of. This is very important for the web. It makes multilingual sites easier to manage since you don't have to worry about any localized character sets for each language. Everything uses the same character set.

In this manner, why is encoding used?

The purpose of encoding is to transform data so that it can be properly (and safely) consumed by a different type of system, e.g. binary data being sent over email, or viewing special characters on a web page. The goal is not to keep information secret, but rather to ensure that it's able to be properly consumed.

Does UTF 8 support all languages?

UTF-8 supports any unicode character, which pragmatically means any natural language (Coptic, Sinhala, Phonecian, Cherokee etc), as well as many non-spoken languages (Music notation, mathematical symbols, APL).
