r - RStudio UTF-8 display issue with htmlwidget:datatable[package DT] -

-

i have dataframe contained chinese chars encoding utf-8.

for example, dataframe below

testdf <- data.frame(locationname= c("台北","新北市","台南市"), temp=c(30,29,28)) testdf   locationname temp 1         台北   30 2       新北市   29 3       台南市   28   library(dt) datatable(testdf)

i found datatable can't display in r viewer (in r console okay) when there have chinese char.

i check index.html generate datatable default using "utf-8"

if manually modify index.html manually to"charset=big5" , using external browser open, okay display. (or choose "show in new windows" , using external browser decode =big5.)

my questions if settings can apply make work in r viewer without manually modify html file manually or view in external browser? help

best regards james
