Well, especially for builtins perl should know if the char* it's handing off to the system call will be interpreted as a classic C string or as a wide character.

I question strongly that this is a serious performance issue - among other things, null-containing strings could easily be flagged as such, the way tainted strings are when running under taint mode.

As for what perl should do, I certainly think that a warning when running under -w is appropriate - this is at least as big a problem as interpolating an undef variable into a string. I might even be convinced that perl in taint mode should treat nul-containing strings as tainted when passing them to C APIs - that is, die.
