Ignore the previous, this bad bug system messed up the input. :)
Here's the actual stuff: http://pecl.php.net/~jani/bug47742.out

This script:
<?php
$s = '&#935;&#953;&#972;&#957;&#953;&#945;,
&#946;&#961;&#959;&#967;&#941;&#962; &#954;&#945;&#953;
&#952;&#965;&#949;&#955;&#955;&#974;&#948;&#949;&#953;&#962;
&#940;&#957;&#949;&#956;&#959;&#953;
&#963;&#965;&#957;&#952;&#941;&#964;&#959;&#965;&#957;
&#964;&#959;';
echo "orig: $s\n";
$s = mb_strtoupper($s);
echo "mb_strtoupper: $s\n";
$s = mb_convert_case($s, MB_CASE_UPPER, "UTF-8");
echo "mb_convert_case (upper): $s\n";
$s = mb_strtolower($s);
echo "mb_strtolower: $s\n";
$s = mb_convert_case($s, MB_CASE_LOWER, "UTF-8");
echo "mb_convert_case (lower): $s\n";
?>

Outputs:

&#963;&#965;&#957;&#952;&#941;&#964;&#959;&#965;&#957;
&#964;&#959;

And this is quite correct..

in both test scripts i provided yesterday, the character set is unicode

and the encoding is utf-8.

in the short test script that i provided 4 May 7:02pm UTC, there is
only 
one short Hangul test string and no Greek, as you said.

in the longer test script i provided at 4 May 5:00pm UTC, several 
alphabets are used including Greek, Cyrillic, Hebrew, Arabic, Thai, 
Kanji, ...

in case it makes life easier for you, i put the longer test script on a

web server: http://tomworster.net/test.php.gz 
it's only 1kbyte.

One last question: What is the charset you used? I don't see any greek

chars anywhere.. ;)
