move_uploaded_file with asian characters uploads to folder with wrong name - php

Question

I'm trying to make a website where you can upload flash .swf files. It works great and all except whenever a user uploads a flash file name with japanese or any other asian characters (tested with Japanese characters) it gives me the name wrong.
So this is the file:
Before it starts moving the file im putting the information in the database.
Database:
flash_id | flash_name | not relevant | flash_size | flash_date
After putting the flashes information in the database I move the file from the tmp folder to another folder where I store the uploads.
If you compare the file names from the first 2 pictures with the third one you can see it isn't the same.
Here is the code:
The variables map, filename and ext below are the values that were used in the moving process.
$map = 62;
$filename = $_FILES['upfile']['name'];
$ext = swf;
$str = "../uploads/$map/$filename.$ext";
if (!move_uploaded_file(
$_FILES['upfile']['tmp_name'],
//sprintf('../uploads/%s/%s.%s',$map,$filename,$ext)
$str
)) {
// Failed to move uploaded file.
throw new RuntimeException(4);
} else {
try {
$insq = $pdo->prepare('INSERT INTO flashes (flash_name, flash_size) VALUES (?,?)');
$insq->bindParam(1, $filename);
$insq->bindParam(2, $filesize);
$insq->execute();
} catch (PDOException $ex) {
throw new RuntimeException(999);
}
}
// File is uploaded successfully.
echo 10;

I could not find a solution for this. So instead of trying to fix this I followed tttony's comment and made it so that the file_names are randomized and the file_name before randomizing is put in the database. So we can show it on our website with its original name however when we are going to download it we will receive a randomized file_name. However if you use the html download="original_file_name" attribute you can still make the user download it with the original file_name.
