That is one Clever Idea Dave.

I take it that the charset of the file 'junk.txt' gets identified by the characters encoding that read form within the file?

But wait a minute: What editor do you uses to write these 3 lines?
I mean am a bit confused.

i for example i 'nano tets.py' which has within:

f = open("junk.txt", "w") 
f.write(b'\xb6\xe3\xed\xf9\xf3\xf4\xef\xfc\xed\xef\xec\xe1 \xf3\xf5\xf3\xf4\xde\xec\xe1\xf4\xef\xf2\n') 
f.close() 

then when i save the file within nano for example by default in utf-8 charset

how would it be able to detect the bytestring within that is supposed to be of greek-iso's
