)

if (interactive()) htmltools::html_print(page)

function (x, escape_reserved = TRUE, csi = c("drop", "keep")) 
{
    if (!is.character(x)) 
        x <- as.character(x)
    csi <- match.arg(csi)
    x <- enc2utf8(x)
    if (escape_reserved) {
        x <- gsub_("&", "&", x, fixed = TRUE, useBytes = TRUE)
        x <- gsub_("<", "<", x, fixed = TRUE, useBytes = TRUE)
        x <- gsub_(">", ">", x, fixed = TRUE, useBytes = TRUE)
