I am surprised to see a sudden error where my ShinyApp stopped working with an unknown error saying 'input string 1 is invalid UTF-8'. Even on yesterday, that App was working perfectly, however, stopped all sudden.
Below is the description of the error when I run runApp()
> runApp()
Listening on http://127.0.0.1:3726
Warning: Error in sub: input string 1 is invalid UTF-8

Have someone faced with similar error? Appreciate for any pointer on how to fix this error. I searched over net for a while for its solution, however didnt find any relevant.
Thanks for your time.
Thanks,
