* functions like fopen(). Windows uses UTF-16, which requires a different

|

|
|
* 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.
