Hello,
I found the problem. BOM: Byte Order mark
Normally under windows a UTF-8 file starts with a BOM (byte order mark, U+FEFF), as is standard for UTF-8 files on Windows systems. I concede that it is legal for them to do so, but it is utterly pointless since the byte order is determined by the formal specification of the UTF-8 representation itself. And it just happens that, unlike the rest of UTF-8, an initial BOM will screw up a Unix system. And Perl is supposed to be

"an oasis of Unix culture in the desert of can't-get-there-from here" (Larry Wall, probably slightly misquoted).
Using a hex editor I removed the FEFF and it worked like a charm.

On Linux you should have no problem, since this aberration does not exist ina Unix system

Many thanks for trying to solve the mystery.

As an aid to all of us who suffer the tyranny of the WinOS system, here is a useful link:

This offers two solutions for the problem. Googling

"perl bom" or "perl File::BOM"
comes up with more if needed.
