Windows encoding utf-8 in shiny verbatimTextOuptut


#1

The string "папка0" prints out fine in Rstudio and Shiny on macOS. However, on Windows it only prints OK in RStudio but not in Shiny verbatimTextOuput. See below. I checked that the encoding of the string is UTF-8. Any suggestions on how to fix?

library(shiny)

ui <- fluidPage(
  actionButton("prn", "Print"),
  verbatimTextOutput("prn")
)

server <- function(input, output) {
  observeEvent(input$prn, {
    print("папка0")
  })
  
  output$prn <- renderPrint({
    print(input$prn)
    print("папка0")
  })
}

# Run the application 
shinyApp(ui = ui, server = server)
