Thank you for your amazing plugin, "Easyfileshop". I like your concept, and it's really helpful to me.
Here is a deal. After clicking "Buy Now!" button PayPal shows an error message on the following.
"Data does not match input character set or default encoding. For more information, please contact the merchant."
My site is in Japanese. This will happen on other languages too I guess. Could you check it?
Additionally I would like to make Japanese translation files if you add the "load_plugin_textdomain".
