In my profile Language Encoding,
I have set to UTF-8 encoding.
The message I received include charset parameter, and the value is UTF-8
I tested item name with Chinese chararcter,
And my IPN listener sends messages back to Paypal,
it receives INVALID.
If I use item name with English only,
the listener receives VERIFIED.
I have tried to use urlencoder to encode the message in UTF-8, and it still INVALID.
Anyone know how to fixed?
Thanks.
