No, there is no locale support on cygwin. Quoting the man page: "isprint
returns non-zero if its argument is a printing character (`0x20'-`0x7E')."
So it should return zero for any non-ascii character, but if I use
\pdfauthor{à} dt2dv succeeds, whereas with \pdfauthor{ö} it fails.
I plan to debug this strange thing.
