0xEDA7A1 (UTF-8) corresponds to UNICODE code point 0xD9E1, which,
when interpreted as a high surrogare and followed by a low surrogate,
would correspond to the UTF-16 encoding of a code point
between 0x88400 and 0x887FF (depending on the value of the low surrogate).

These code points do not correspond to any valid character.
So - unless there is a flaw in my reasoning - there's something
fishy with these data anyway.

Janine, could you give us a hex dump of that line from the copy statement?
