I'm trying too!
So,
chr('A') would give me the mapping of this char, the number 65 while
ord(65) would output the char 'A' likewise.

What would happen if we we try to re-encode bytes on the disk?
like trying:
s = "νίκος"
utf8_bytes = s.encode('utf-8')
greek_bytes = utf_bytes.encode('iso-8869-7')
Can we re-encode twice or as many times we want and then decode back respectively lke?
utf8_bytes = greek_bytes.decode('iso-8859-7')
s = utf8_bytes.decoce('utf-8')
Is somethign like that totally crazy?
And also is there a deiffrence between "encoding" and "compressing" ?
Isnt the latter useing some form of encoding to take a string or bytes to make hold less space on disk?
