Hello Guido,
First of all I think I should ask myself If I want to take up
challenges with you :)
anyway I am going to let loose in the hope that I will learn somthing new.
I can think of a byte array coming of a socket containing EBCIDIC for
instance . I want to store this in a string type and hand it off
to a translation function that can translate from EBCIDIC to ASCII
.storing the encoding in the string as an attribute will help the
translation function. At this point I am thinking why should I pass this
as a parameter to the translation function rather than store it as an
attribute of the string object itself. The translation function knows it
has to produce US-ASCII, so it looks at the encoding attribute of the
input string and figures out what to do from there.
