For the record, I have scripts that can generate ISO-8859-* to/from
unicode tables from the downloaded data; I'll happily contribute this
if it is useful to anyone.

I liked that idea of making them obviously-unsigned; I had some nasty
bugs with my UTF-8 code where I made invalid assumptions about signs.
But of course being consistent with C++0x is more important.

Agreed. Mathias, I would love to see a sort of "end user perspective"
view of how this library will be used, i.e. its scope and basic usage pattern.
