I'm using Paypal Rest API SDK to "Create a payment". However, when I add Item objects with Chinese characters as "name", it returns server error 400: Must contain only these characters: a-z, A-Z, 0-9, punctuation(.,#-‘), and embedded spaces). The same constraints apply to shipping address. Is it a limitation of the Rest API? It seems quite a harsh constraint. Must I revert to the classic API in order to use non-alphanumeric strings?
Thanks
