Accent mark in R-Shiny app

Question

I am new to shiny and am trying to input html tags for adding some header text but the words that contain an accent mark (as very usual in spanish) results in error. For example, the code below produces what I want:

library(shiny)
ui <- fluidPage(

  titlePanel("Titles"),
    sidebarLayout(
      sidebarPanel(  
        tagList(tags$h4("Geological Survey of Colombia"),
                tags$h2("Analitic Geochemistry Group"),
                tags$p("Text here"))),

    # Main panel for displaying outputs ----
    mainPanel()
    )
    )
server <- function(input, output) {}
shinyApp(ui, server)

But changing tags$h4("Geological Survey of Colombia") for tags$h4("Servicio Geológico Colombiano") results in the error:

 Warning in checkEncoding(file) :   The input file
 C:\Users\cparedes\Documents\Shiny\test/app.R does not seem to be

How can Include the accent marks?

Answer 1

You can solve this with "Save with encoding" your file in UTF-8. I had the same issue with accent marks and used this guide https://shiny.rstudio.com/articles/unicode.html
