Encoding utf-8 and decode to iso-8859-16

Im trying to understand how the transformation from utf-8 to other encodings work.

In this example:- I have a string that I encode with 'utf-8' and decode with 'iso-8859-16'.
Just trying to understand, how a extra byte is added during transformation?

>>> r_post='Hello Günter'
>>> r_post=r_post.encode('utf-8')
>>> r_post
b'Hello G\xc3\xbcnter'
>>> r_post=r_post.decode('iso-8859-16')
>>> r_post
'Hello GĂŒnter'

Answer Source
Hello G\xc3\xbcnter

This is a byte string, with the two bytes used for 'ü' conveniently highlighted. In the UTF-8 encoding, the character 'ü' is represented by the two bytes C3 BC.

Reading those bytes and interpreting them in the ISO-8859-16 encoding gives you the characters "Hello GĂŒnter". In 8859-16, the byte C3 represents the character 'Ă' and BC represents the character 'Œ'.
