I wanted to know how i could write the file (now a string) as a jpeg image on disk. When I try to encode the same string to a bytes and write them in binary format to disk, the file is not recognized as jpeg. I would be grateful if someone could help me with this.

Also, my apologies for lack of knowledge of character encodings. You have pointed out correctly about unicode encoding. I was under the impression that a unicode will preserve the integrity of the message which has been encoded.
