通過OneSignal發送帶有口音（á，é，í）的推送通知的問題

Question

每當我嘗試通過OneSignal發送帶有口音（á，é，í）的推送通知時，我的手機上都會出現空符號。

Answer 1

我固定的編碼我的信息這一問題作爲UTF-8：

String payload = "{" 
    + "\"app_id\": \"" + APP_ID + "\"," 
    + "\"filters\": [{\"field\": \"tag\", \"key\": \"company\", \"relation\": \"=\", \"value\": \"" + companyID + "\"}]," 
    + "\"data\": {\"foo\": \"bar\"}," 
    + "\"contents\": {\"en\": \" " + notification + "\"}" 
    + "}"; 

byte[] data = payload.getBytes("UTF-8"); 

我還設置Content-Type爲application/json; charset=UTF-8。
