How to add subscript or superscript to renderText in R shiny

Is there a way to add html text formatting (such as superscript or subscript) to the output of renderText(). It seems that html tags don't work in this context.

Minimal example:

library(shiny)

ui <- fluidPage(
    titlePanel("Subscript test"),
    mainPanel(textOutput("test"))
    )

server <- function(input, output) {
    output$test <- renderText("CO<sub>2</sub>")
}

shinyApp(ui = ui, server = server)

Your code just needs the textOutput() in the ui section to be changed to htmlOutput(). The latter function is specifically designed to return a reactive variable as HTML output, which allows for the usage of HTML tags among others.
