What "binaries" are you talking about?

I mean extension modules with native code, which means .so shared library files on unix.

AFAIK, C extensions should fail loading when they have the wrong UCS2/4 setting.

That would be an improvement! Unfortunately we instead get mysterious misbehavior of the module, e.g.:

For information, all Mandriva versions I've used until now have had their Python's built with UCS2 (maxunicode == 65535).

Thank you for the data point. This means that binary extension modules built on Mandriva can't be ported to Ubuntu or vice versa. However, is this an argument for or against changing the default setting to UCS4? Changing the default setting wouldn't interfere with Mandriva's decision, right?
