I was rereading the archives and found this one, and since no one answered I think I'll give my opinion :-) On Fri, 2002-09-13 at 14:19, Ralf W. Grosse-Kunstleve wrote:

Consider

char foo() { return '\0'; }

Python with Boost.Python V1: foo() == "" Python with Boost.Python V2: foo() == "\0"

Is this difference intentional?

I don't know :-)

I'd prefer the V1 result. Opinions?

If you're returning a C/C++ char in a wrapped function to python, I think it should always return something such that len(foo()) == 1. I'd prefer the V2 result, as I believe it sits better with the 'Explicit better than implicit' Python rule.
