My codecvt (a.k.a. facet) never gets called.

26 Nov 2009 by Stuart Dootson

From what I can tell, the C++ stream system presumes that files are sequences of bytes, not characters - even when you use wide streams - the 'wide' part of wide stream (AFAICT) indicates how the stream object interacts with C++, not the underlying file or whatever. Thus, your codecvt facet has to t
