Your explanation of encoding/decoding is excellent and iam storing this Steven!
So what i understand now is:

encoding = string -> (some charset used) -> charset bytes
decoding = bytes -> (have to know what charset has been used) -> original string

Have i understtod corrctly, that the *key* to the whole encode/decode process is the charset used/has to be used?

string = 'Ευχή του Ιησού.mp3'
abive string in unknown charset bytes = '\305\365\367\336\364\357\365\ \311\347\363\357\375.mp3'

We dont know they key(charset) used, but we do know the original form of the string, so it occured to me that if we write a python script to decode the mojabike bytestream to all available charsets then as some point the original string will appear back!


Won't you agree steven? Of course if that is likeley to work i don't know how to write it.


Hre is the comamnds you asked.

I uploaded via FileZilla the files with english chars and then reanmes from CentOS, i did that to avoid renaming them from within my Win8. I though it was betetr to rename form within linux itself.
