Escape characters

[Csag-parel]

Hello,

We encountered an issue with escape characters when processing payments for Bulgaria through GoPay. After contacting GoPay support, we were informed that the presence of escape characters causes their system to treat the request as a potential threat, which leads to it being rejected.
To resolve this, could you please add functionality to specify the JSON_FLAG parameter in the json_encode() function used in the encodeData() method in gopay-php-api/src/GoPay.php?

Thank you for your assistance.

Hello,

please make sure you use UTF-8 encoding for all incoming and outgoing communication.

If you are using UTF-8 encoding and an error occurs, please specify for which e-shop (EVC, GoID) exactly
when the error occurs, send samples (screens, log with errors).

Hello,

I'm sorry, but unless you use UTF-8 encoding for all API communication, you can't avoid incorrect escaping by the gateway.

This cannot be influenced by the gateway.

Hello,
we are using UTF-8 encoding but json_encode in default setting this characters escapes

Hello,
I did another check to prove my claim that the texts for gopay are in UTF-8. Below you have the code I used. There is both a test of Czech characters and the data that we send to the gopay api without information about the customer. It is demonstrated here that the character encoding is in UTF-8 and json_encode is still escape. That is why a fork of your SDK for php has been created https://github.com/Csag-parel/gopay-php-api but we would be happy if you fixed it in your official SDK.
Thank you

CODE:

var_dump(json_encode(['testCZ' => 'ěščřžýáíé']));
        var_dump(mb_detect_encoding('ěščřžýáíé'));
        var_dump($normalizedPayment);
        foreach ($normalizedPayment['items'] as $key => $value) {
            var_dump($key);
            var_dump($value['name']);
            var_dump(mb_detect_encoding($value['name']));
        }
        var_dump(json_encode($normalizedPayment));
        die();
