PayPal: Data does not match input character set...

Hello,

In the last 24 hours, 2 customers have tried to buy products on my bilingual store (English & Japanese) but in the last step, when the store redirects to the PayPal site they get the following message:

Data does not match input character set or default encoding. For more information, please contact the merchant.

Both were using Japanese as their main languages. One was using windows, one a Mac using Firefox and then Safari... I saw the problem myself as it was a friend who wanted to do the purchase and I visited them to see for myself.

I just tried using Japanese with a Mac using Safari and FireFox and there were no problems...

Does anyone have any ideas on what might be the problem? Any testing suggestions?

Thanks!

The patch I posted here should be set to pass the desired CHARSET to paypal... not sure if that's what you're after:

Would like to know if it resolves the situation for you.

Hello Dr. Byte,

Thank you for your quick response!

Wanted to let you know that it appears to have solved the problem. One of the people has retested and says it is now OK. I am still waiting for the other. When I hear from them I will confirm.

Once again, thank you!

Hi Dr. Byte,

The second person could log in to PayPal!

Thanks!
