Japanese Moodle

Could you find the Moodle install directory?
Then go to "lib" directory in the Moodle install directory.

The script file you need to modify is "dmlib.php" in "lib" directory.
Open dmlib.php and go to line 1909.
And modify the "code" as below.

[Before]
switch ($CFG->dbtype) {
case 'mysql':
/// Set names if needed
if ($CFG->unicodedb) {
$db->Execute("SET NAMES 'utf8'");
}
break;

[After]
switch ($CFG->dbtype) {
case 'mysql':
/// Set names if needed
if ($CFG->unicodedb) {
// $db->Execute("SET NAMES 'utf8'");
}
break;
