Different representations of multibyte encodings may be generated by:

1. Bin = list_to_binary([209,130,208,181,209,129,209,130]) - byte
string like <<209,130,208,181,209,129,209,130>>, ready for
sending to others programs/clients, storing, etc.

2. unicode:characters_to_list(Bin) -> [1090,1077,1089,1090].
A list of chars. Every char is represented using one integer.
