How to display non-English (Japanese/Chinese) characters/text in Shiny on Windows? (NOT ABLE TO ENCODE)

Hello,

I am not able to display non- English characters in Shiny. Is it a bug in RStudio on Windows? I have tried many ways which I found through internet search but nothing has worked for me. I have even called Sys.setlocale(category="LC_ALL", locale = "en_US.UTF-8") in .Rprofie but still didn't work. I followed all the instructions in https://support.rstudio.com/hc/en-us/articles/200532197-Character-Encoding and http://shiny.rstudio.com/articles/unicode.html hoping to find a solution but no such luck.

Can anyone please help me resolve this issue. I have been working on this for many hours so I am reaching out to this forum hoping to find a solution.

Thanks.
