This is incorrect. While in UTF-32 a character (actually a code point) requires 4 bytes, and in UTF-8 up to 4 bytes, the Unicode standard is limited to 17*2^16 code points. (edit: apparently because that is the limit of UTF-16. 4 Byte UTF-8 can encode 2^21 code points, but it is not technically limited to four bytes, so in total is a ble to encode 2^31 code points)
Unicode is the standard that says “the thing we call captial A is the 65th character”, literally defining a mapping from numbers to concepts.
UTF-8 or UTF-32 are a way to encode a list of numbers in a more (UTF-8) or less (UTF-32) efficient way.
