Hi~
 
I found some problem when using non-english language for the checkout page. After redirect to Paypal make payment, it will should a language error code
 
Here is my setting
Paypal Language = UTF-8
Viart system default language is English
 
I test with a test account France customer and click the France language, but when I click checkout, it redirect to paypal make payment. It's will show some error message
 
But if I return back to English, it is OK for checkout.
 
Is this any idea or suggestion?
 
Thanks
