Game Development Dictionary
Unicode is a standard which describes character encoding, similar to ASCII. However, in contrast to ASCII and other encodings, Unicode tries to encompass all characters ever needed. While ASCII is limited to one-byte units and therefore 256 different characters, Unicode uses three different encoding forms: UTF-8 uses 8-bit units; UTF-16 uses 16-bit units; UTF-32 uses 32-bit units. All three of these forms can make use of all characters covered by the standard; in UTF-8 and UTF-16, a character may however consist of more than one unit.
