I liked your earlier comments, but not this one: I'm not much interested 
in broad, purely associative hints.

It's not bad as a first idea when confronted with the issue.

But you can be sure that every person who has confronted that issue, 
including me (but evidently not yourself), has tried it out.

Anyway, to find out the reasons why the locale/facet approach is 
misguided and non-working, you can read my blog postings. :-)

But if a shallow reason is enough, just note that the standard streams 
from <iostream> are not required to honor an imbued locale's codecvt 
facet, and that while that works with Visual C++, the g++ compiler does 
take advantage of the standard's license to not support it. A file 
stream buffer, on the other hand, is explicitly required to use the 
codecvt facet of the imbued locale. See, you learned something today!

I hope that people here can form their own opinions both about the 
alleged facts and how relevant it.

But as it happens, if you'd but click on the link and look at what you 
have so strong opinions about, you'd find an edit field for feedback.


Cheers & hth.,
