* Unicode character type. For Linux and Mac OS X, filenames use "narrow"
* characters and UTF-8 encoding, which allows them to use standard file I/O
* functions like fopen(). Windows uses UTF-16, which requires a different
* character type and an alternative set of I/O functions like _wfopen().
*
* The idea is that NufxLib API functions will operate on filenames with
* the OS dominant method, so on Windows the API accepts UTF-16. This
* definition is a bit like Windows TCHAR, but it's dependent on the OS, not
* on whether _MBCS or _UNICODE is defined.
*
* The app can include "Unichar.h" to get definitions for functions that
* switch between narrow and wide functions (e.g. "unistrlen()" becomes
* strlen() or wcslen() as appropriate).
*
* We switch based on _WIN32, because we're not really switching on
* filename-character size; the key issue is all the pesky wide I/O calls.
