[Python-Dev] "embedded NUL character" exceptions

[Serhiy Storchaka]

Currently most functions which accepts string argument which then passed 
to C function as NUL-terminated string, reject strings with embedded NUL 
character and raise TypeError. ValueError looks more appropriate here, 
because argument type is correct (str), only its value is wrong. But 
this is backward incompatible change.

I think that we should get rid of this legacy inconsistency sooner or 
later. Why not fix it right now? I have opened an issue on the tracker 
[1], but this issue requires more broad discussion.
