The problem exists In WordPress 2 with coding (charset) trackbak.
Reception XML-request from trackbak is executed by means of file wp-trackback.php. In he is indicated:
$charset = $_POST['charset'];
But, when sending trackbak, importance charset is not indicated.
The Error is situated in file functions.php (function trackback):
$query_string = "title=$title&url=$url&blog_name=$blog_name&excerpt=$excerpt";
It is Correct:
$query_string = "title=$title&url=$url&blog_name=$blog_name&excerpt=$excerpt&charset=" . get_settings('blog_charset');
The Error much aging, request to developer to correct.
ps Excuse me me for english - use google-translator.
