What is Unicode?
Nowadays, the most common character set used is Unicode. Each unicode character can be encoded on a computer with 3 different encoding standards, which differ based on the minimum number of bits used.
Over a million possible characters, different languages than English were able to make a debut and have their own characters included. Like chinese, russian or korean, etc.
UTF 8 = most common 8-bit unicode format. can expand to 16,32,40 or 48 bits.
UTF 16 = 16 bit allows variable-width encoding, can expand to 32 bits
UTF 32 = Each character uses exactly 32 bits, this is an example of fixed-width encoding
