'b' stands for binary right? 
 b'\xce\xb1' = we are looking at a byte in a hexadecimal format? 
if yes how could we see it in binary and decimal represenation?

Since 2^8 = 256, utf-8 should store the first 256 chars of unicode charset using 1 byte. 

Also Since 2^16 = 65535, utf-8 should store the first 65535 chars of unicode charset using 2 bytes and so on. 

But i know that this is not the case. 
But i dont understand why.

EBCDIC and ASCII and Unicode are charactet sets, correct? 

iso-8859-1, iso-8859-7, utf-8, utf-16, utf-32 and so on are encoding methods, right?
