R Leaflet中的字符编码

Question

我有一个带有多种语言值的数据框。

我正在尝试在传单地图中使用它，但是我无法使编码正常工作。

我意识到相关的编码是“ UTF-8”。

我尝试了建议使用here的解决方案，但对我而言不起作用。

最小示例代码：

options(encoding = "UTF-8")
library(leaflet)

df <- data.frame(
  name = c("Europe", "ხარებაშვილი", "喬治亞"),
  lng = c(40, 40.5, 41),
  lat = c(70, 70, 70)
)

leaflet(data = df) %>% 
  addCircleMarkers(label = ~name, labelOptions = labelOptions(permanent = T))

最小示例屏幕截图：
