(ok 3.0.0-rc1) Not usable config var DefaultCharset

In documentation we have this description:
$cfg['DefaultCharset'] string
Default character set to use for recoding of MySQL queries. This must be enabled and it's described by $cfg['AllowAnywhereRecoding'] option. You can give here any character set which is in $cfg'AvailableCharsets'] array and this is just default choice, user can select any of them.

As I unerstood, this directive is used on both pages Import and Export, to highlight default encoding charset option. But it's not using at all. On Export page we have another directive that makes exactly the same - $cfg['Export']['charset']. Strange logic, think it should be clear up. If we use $cfg['Export']['charset'] - let's make $cfg['Import']['charset'] that will take place on Import page. Or we have to use $cfg['DefaultCharset'] on Import and Export pages? May be this directives is useless and it would be better to delete them at all?

There is a little mess in code that combine options from array. Below is my suggestions for this part of code.

libraries/display_export.lib.php, line 206.

if ($cfg['AllowAnywhereRecoding'] && $allow_recoding) {
echo ' <label for="select_charset_of_file">'
. $strCharsetOfFile . '</label>' . "\n";

echo ' <select id="select_charset_of_file" name="charset_of_file" size="1">' . "\n";
foreach ($cfg['AvailableCharsets'] as $temp_charset) {
echo ' <option value="' . $temp_charset . '"';
if ((empty($cfg['Export']['charset']) && $temp_charset == $charset)
|| $temp_charset == $cfg['Export']['charset']) {
echo ' selected="selected"';
}
echo '>' . $temp_charset . '</option>' . "\n";
} // end foreach
echo ' </select>';
} // end if

/* As possible variant.

if ($temp_charset == $charset) {
echo ' selected="selected"';
}

}

} else {
echo '<label for="charset_of_file">' . $strCharsetOfFile . '</label>' . "\n";

} // end if (recoding)
