if necssary for the font. But you still have the problem that
not all fonts have all Unicode characters.) If your outputting
to std::cout, in an xterm, however, you have absolutely no means
of knowing. And if you're outputting to a file, with the idea

It depends. At least under Unix with X, locale and the font
encoding are completely independent. And neither can really
solve the most basic problem: if I write to a file, what should
I write if the file will later be copied to two different
devices, using two different encodings?
The problems are far from simple. On the whole, I'd say when in
doubt, use UTF-8, and I'd certainly opt for UTF-8 for most new
uses. But legacy code and legacy environments won't go away
like that: where I work, for some reason, there are no UTF-8
fonts installed (for X); at home, I still have an old printer
which only understands ISO 8859-1, etc.
