So this is the same issue with char being unsigned on your platform.
Specifically, it seems the corresponding __reduce__ function converts a char
array into a list of python ints, which has range 0-255 for you, instead of the
-128-127 on x86. And the unpickle function has the opposite issue.
I wonder how many of these are around, and if there is any general fix for
them.
Well, if there is a nice inheritance graph, there's hope fixing the base
class will maket the rest just go smooth.
Now, to fix the base class... If the goal is to take a "char" on one
platform and turn it into a "char" on another, then it's a lost battle.
What are those "char" really encoding? If they are really "foo", then
turning a "foo" on one platform into a "foo" on another might not be
impossible!
