R闪亮外来字符编码

Question

我们正在收集音乐家数据，其中包含外国字符（西班牙语，中文，韩语等）的音乐家名称。我想我必须指定编码，我陷入困境。以下是我的临时解决方案，适用于英语+西班牙语名称。

#if I don't specify encoding = "Latin-1", they will not display any foreign names correctly. 
#By setting encoding = "Latin-1", it makes sure Spanish names display correctly. 
#However, it doesn't work for Asian characters. 
dd = fread(paste0("/shiny-server/testingfile.csv"), encoding = "Latin-1")

#to download it and show names correctly, I also need to set fileEncoding = "latin1"
output$map = downloadHandler(
filename = function(){
  paste("Mapping Request ",Sys.time(),".csv",sep="")
},
content = function(file){
  write.csv(data,file,row.names = F,fileEncoding = "latin1")
}
)

我想知道有没有办法让任何外国名字正确显示？或者我必须为每种语言设置编码（这是不实际的）。当我设置encoding =＆＃34; UTF-8＆＃34;时，它只能正确显示英文名称。

顺便说一句，我们的Shiny-server是Linux。

提前谢谢你。
