title: Paypal gateway rejection currency not supported in magento
body: <p>My base currency is Chinese RMB in admin side. I do not want to change base currency and my display currency is also Chinese RMB. My payment method is PayPal standard. When I order through PayPal in front side following error occurs.</p>
  
  <p><code>PayPal gateway has rejected request. Currency is not supported (#10605: Transaction refused because of an invalid argument. See additional error messages for details). Internal Error (#10001: Transaction failed due to internal error).</code></p>
  
  <p>Can anybody tell me how to fix it without changing base currency?</p>
