ASCII vs. Unicode vs. UTF-7 vs. UTF-8 vs. UTF-32 vs. ANSI
Both ASCII and Unicode are encoding standards. ASCII is an initial standard that was first published in 1963, whereas Unicode is a larger standard. Unicode standards are implemented by either UTF-8, UTF-16, or UTF-32. ANSI is a misnomer of a Windows encoding standard but is not recognized by ANSI itself.
