excellent

also good.

so what are we talking about?

LOL - So what I'm hearing here that there is already the codecvt facet 
created as part of Boost.Locale and all we need is to enhance the 
documenation in order to make it more obvious to those of us that need 
it.  I've been hoping all along that we've have something like this. 
Some time ago I have Boost.Locale a cursory look in search of such a 
thing.  It's quite possible it's always been there and I didn't see it,
that's it's "implicit" and obvious to someone who has read and 
understood he rest of the documentation, or that the library has evolved 
since I did this or all of the above.  In any case I'm very interested 
in this.

OK - do this and let us know, I'll look it over again and give you some 
feedback from a novice.

LOL - you do your part - and the rest will happen.
