R編碼與源代碼錯誤，但不是在控制檯中

在R-Studio中使用源代碼時，我遇到了一些奇怪的編碼問題，但在開發腳本時直接按Ctrl + Enter時沒有。基本上，我創建一個data.frame存儲來自不同語言的單詞以及他們的英文翻譯。這工作正常，直到我來源。我意識到這可能是編碼問題，但我真的不知道如何繼續，也不完全明白爲什麼我得到的錯誤（意外的INCOMPLETE_STRING）只發生在源代碼中。在每次更改語言之前是否需要更改編碼？我怎麼知道哪個編碼是正確的？R編碼與源代碼錯誤，但不是在控制檯中

感謝您的任何幫助。以下是代碼：

translator = data.frame('RESULT' = character(),'english' = character(),stringsAsFactors = FALSE) 

translator[1,] = c('Completed','Completed') #English 
translator[2,] = c('Failed','Failed') #English 
translator[3,] = c('User canceled','Canceled') #English 

translator[4,] = c('完了','Completed') #chinese 
translator[5,] = c('已完成','Completed') #Chinese 
translator[6,] = c('失敗','Failed') #Chinese 
translator[7,] = c('用戶取消','Canceled') #Chinese 

translator[8,] = c('ユーザーによる取り消し','Canceled') #japanese 
translator[9,] = c('エラー','Failed') #japanese 

translator[10,] = c('Completata','Completed') #Italian 
translator[11,] = c('Fallita','Failed') #Italian 
translator[12,] = c('Annullata','Canceled') #Italian 

translator[13,] = c('Finalizado','Completed') #Spanish 
translator[14,] = c('Cancel usuario','Canceled') #Spanish 
translator[15,] = c('Fallido','Failed') #Spanish 
translator[16,] = c('Cancelado utili.','Canceled') #Spanish 

translator[17,] = c('Terminé','Completed') #French 
translator[18,] = c('Annulé par utilis.','Canceled') #French 
translator[19,] = c('Echoué','Failed') #French 

translator[20,] = c('Abgeschlossen','Completed') #German 
translator[21,] = c('Benutzerabbruch','Canceled') #German 
translator[22,] = c('Fehlgeschlagen','Failed') #German 

translator[23,] = c('Concluído','Completed') #Portuguese 
translator[24,] = c('Falhado','Failed') #Portuguese 

translator[25,] = c('Doko','Completed') #Czech 
translator[26,] = c('Zru','Canceled') #Czech 

translator[27,] = c('Chyba','Failed') #Polish 

translator[28,] = c('Отмена','Canceled') #Russian 
translator[29,] = c('Готово','Completed') #Russian 
translator[30,] = c('Ошибка','Failed') #Russian
