I'm not opposing the question. There is something I want to know there too,
but I don't want to usurp Zach's question so I am asking him what he meant.

In your case, for example, if you're dealing with UTF-8 on Windows, which is
the proper answer:
a) I only use one encoding, which is a Unicode one

b) I use two encodings, UTF-8 for my file's contents and UTF-16 because all my
system calls are UTF-16. This may even be three encodings, depending on just
which API you're using to open those files in the first place -- if you've used
fopen(), it's probably CP_ACP.
