收款存在三大问题：
我们公司经营匈牙利产品，包括重音字符的产品描述。新的 RestAPI 可以成功管理支付解决第一轮，但我不能重音字符通过贝宝服务器。
如果我正在使用 HTML.Encoding，则结帐页面上将显示的密文不会解码 Paypal 服务器。（环境：Windows、.NET、C#）
所以：
1.如何在项目名称中使用重音字符？
更新：
我尝试了 UTF8 如下：
1.1。获取访问令牌：
curl https://api.sandbox.paypal.com/v1/oauth2/token \
-H "Accept: application/json" \
-H "Content-Type: charset=UTF-8" \
-H "Accept-Language: hu_HU" \
-u "EOJ2S-Z6OoN_le_KS1d75wsZ6y0SFdVsY9183IvxFyZp:EClusMEUk8e9ihI7ZdVLF5cZ6y0SFdVsY9183IvxFyZp" \
-d "grant_type=client_credentials"

{"scope":"openid https://api.paypal.com/v1/payments/.* https://api.paypal.com/v1/vault/credit-card/.* https://api.paypal.com/v1/vault/credit-card
https://api.paypal.com/v1/developer/.*",
"access_token":"5tz416Qgym8Si9RM0nBS4DNSrGRFCMu5vZ923s--hLM",
"token_type":"Bearer",
"app_id":"APP-8KK24973T6066201W",
"expires_in":28800
}
1.3. 内容 json（我用记事本保存为 UTF-8 文本文件，名称为“content-utf8.json”）
{
"intent":"sale",
"redirect_urls":{
"return_url":"http://example.com/your_redirect_url/",
"cancel_url":"http://example.com/your_cancel_url/"
},
"payer":{
"payment_method":"paypal"
},
"transactions":[
{
"amount":{
"total":"7.47",
"currency":"USD"
},
"description":**"Árvíztűrő tükörfúrógépes tanfolyam"**
}
]
}
1.4. 发送付款
curl -v https://api.sandbox.paypal.com/v1/payments/payment \
-H 'Content-Type:application/json; charset=utf-8' \
-H 'Authorization:Bearer 5tz416Qgym8Si9RM0nBS4DNSrGRFCMu5vZ923s--hLM' \
--data 'content-utf8.json'

我们计划为来自不同国家的客户提供服务，因此如果通过 PayPal 支付页面（如果语言支持）以他们的语言显示，那就太好了。
2. Paypal的approval_url页面返回英文/匈牙利文（或paypal支持的任何其他语言），我该如何解决？
当付款客户重定向到您可以使用信用卡付款的 PayPal 网站时，您应该填写一些字段（名字、姓氏、地址、电话等）。如果我们可以检索这些字段转发数据，Tulum 会很好。

3.我如何通过PayPal RestAPI（或其他方式）在PayPal付款之前将客户端数据发送到服务器？
任何帮助表示赞赏！
