Re: UTF-8 support - char or wchar_t?

But not necessarily codecvt_byname<char, char, mbstate_t>, which
is presumably what the test case uses. I think the answer depends
on what the narrow internal encoding is in the fi_FI.UTF-8 locale.
If it's, say, ISO-8859-15 then there should be no reason to use
wchar_t.


Indeed, thanks for the puntualization. However, if we expect the
conversion to happen *automatically* during I/O, then fstream uses
codecvt, not codecvt_byname.
