Problem with umlaut (mutated vowel) in PayPal Adr

Hello
I'm using
- Joomla 1.7.3
- HikaShop Starter 1.5.5
- HikaShop Paypal payment plugin
- PayPal Sandbox account (test environment)

In one of my shop client accounts, the adress city contains an umlaut (Schönenberg).

The string (first relevant part only) delivered from PayPal to HikaShop is:

mc_gross=4.40&invoice=8&protection_eligibility=Ineligible&address_status=unconfirmed&item_number1=S_000001_mp3_3&tax=0.00&item_number2=S_000001_mp3_1&payer_id=MKHKD3TRNBYJQ&address_street=SingAlong Buechenstrasse 1&payment_date=00:54:04 Jan 09, 2012 PST&payment_status=Completed&charset=windows-1252&address_zip=8824&mc_shipping=0.00&mc_handling=0.00&first_name=Paul&mc_fee=0.50&address_country_code=CH&address_name=SingAlong&notify_version=3.4&custom=&payer_status=unverified&business=paul.chautems@megaflops.ch&address_country=Switzerland&num_cart_items=2&mc_handling1=0.00&mc_handling2=0.00&address_city=Schönenberg&verify_sign....

After a successful payment, the following broken entry is found in the invoice record.

After changing the adress city to Schoenenberg (instead of Schönenberg), the record delivered by PayPal contains address_city=Schoenenberg and the following, complete entry is found in the invoice record.

Hi,

On which invoice record do you have that ?
In the history of the order when the debug is activated ?
In the payment log ?
Somewhere else ?

Hi
The information I copied and pasted into the bug report are stored
- in table d4adx_hikashop_history
- field history_data

Here is the mysql dump:
INSERT INTO `d4adx_hikashop_history` (`history_id`, `history_order_id`, `history_created`, `history_ip`, `history_new_status`, `history_reason`, `history_notified`, `history_amount`, `history_package_id`, `history_payment_id`, `history_payment_method`, `history_data`, `history_type`, `history_user_id`) VALUES(16, 8, 1326099257, '173.0.82.126', 'confirmed', 'Automatische Zahlungsbenachrichtigung empfangen', 1, '4.40EUR', 0, '1', 'paypal', 'Array\n(\n [option] => com_hikashop\n [ctrl] => checkout\n [task] => notify\n [notif_payment] => paypal\n [tmpl] => component\n [lang] => de\n [Itemid] => 767\n [mc_gross] => 4.40\n [invoice] => 8\n [protection_eligibility] => Ineligible\n [address_status] => unconfirmed\n [item_number1] => S_000001_mp3_3\n [tax] => 0.00\n [item_number2] => S_000001_mp3_1\n [payer_id] => MKHKD3TRNBYJQ\n [address_street] => SingAlong\r\nBuechenstrasse 1\n [payment_date] => 00:54:04 Jan 09, 2012 PST\n [payment_status] => Completed\n [charset] => windows-1252\n [address_zip] => 8824\n [mc_shipping] => 0.00\n [mc_handling] => 0.00\n [first_name] => Paul\n [mc_fee] => 0.50\n [address_country_code] => CH\n [address_name] => SingAlong\n [notify_version] => 3.4\n [custom] => \n [payer_status] => unverified\n [business] => paul.chautems@megaflops.ch\n [address_country] => Switzerland\n [num_cart_items] => 2\n [mc_handling1] => 0.00\n [mc_handling2] => 0.00\n [address_city] => Sch', 'payment', 0);

That's because of the verification which is done by joomla on the request variables. It's the line:
$value = JRequest::getString($key);
in the file plugins/hikashoppayment/paypal.php
If you replace it with:
$value = strip_tags($value);
it will work as it won't use anymore joomla's filtering system.

Hello
Your solution did not solve the mutaded vowel "problem" - because the problem is elsewhere.

The information stored in the 'Information' part (field history_data in record hikashop_history) is stored if the paypal plugin option 'debug' is set. If this option is turned off, no information is stored and everything works fine.

But even if the debug function breaks on a mutated vowel, the payment process works correctly.

So, for me, the "problem" is not a problem any more.

Thanks for help.

Yes, it's only debug information so it's not really important.
Still that should not happen. I don't know why that change wouldn't solve the problem.
