When i am trying to import a csv with posts i am getting the above message. I debugged and this is what i get:

$is_update:

array(4) {
[“post_type”]=>
string(4) “post”
[“post_name”]=>
string(32) “??????? ???????????? ???? ??????”
[“post_title”]=>
string(32) “??????? ???????????? ???? ??????”
[“post_content”]=>
string(1262) ”
? ????? ??????? ??????????? ?? ?????????? ?? ?? ????? ??????????? ??? ????? ??? ?? ???? ?????? ??????? ???? ????????????? ???? ????? ?????? ??? ??????.

???? ??????? ????? ???????? ?????????? ???? ???????????? ??????? ??? ????? ???????.

? ??????? ?? ??????????????? ??? ???? ?????????? ??? 2011 ??? ?? ????? ????????? ??????? 8 ?????? (5/9/11 ? 12/9/11).

??? ???????? ?????????? ??? ???????????? ??????????? ??????????? ???? ?????????????? ?? ??? ???????? ??? ?????? ??????????? ??? ?????, ?? ???? ???????? ??? ???????? 22-453886.

???????? ?????????? ?? ???????? ?????? ????? ??? 15 ??????? 2011.
”
}
$meta:
array(1) {
[“custom_field”]=>
string(0) “”
}
$tax:
array(0) {
}

Mind that the language of the post is Greek. That is why we get strange characters.

Please advise

Thanks
