Because I have no idea about wchar.

Ugh.

I am on linux, but the same source (that uses wchar) is also compiled under
Windows. Since it apparently works on both, I need to emulate both. From
C++ constant strings are passed in as L"SomeString". How do I emulate that
froma Perl e.g. convert a Perl scalar to this?

Ok, which CodePage do I then use? Yes, sorry, I don't know nothing about
codepages, unicode etc.

"Naturally the parameter and boundary of their respective position and
magnitude are naturally determinable up to the limits of possible
measurement as stated by the general quantum hypothesis and Heisenberg's
uncertainty principle, but this indeterminacy in precise value is not a
consequence of quantum uncertainty. What this illustrates is that in
relation to indeterminacy in precise physical magnitude, the micro and
macroscopic are inextricably linked, both being a part of the same parcel,
rather than just a case of the former underlying and contributing to the
latter." -- Peter Lynd
