Overview
Character encoding is the process though which characters within a text document are represented by numeric codes. Depending of the character encoding used, the same text will end up with different binary representations. Common character encoding standards are ASCII, Unicode and UCS.

ASCII
Unicode
Unicode supports a larger character set than ASCII.
Unicode Transformation Format (UTF)
Binary representation of a text represented in Unicode depends on the "transformation format" used. UTF stands for "Unicode Transformation Format", and the number specified after the dash in the transformation format name represents the number of bits used to represent each character.
UTF-8
UTF-16
UTF-16 support a large enough character set to represent both Western and Eastern letters and symbols.
