html_encoding_guess() helps you handle web pages that declare an incorrect encoding. Use html_encoding_guess() to generate a list of possible encodings, then try each out by using encoding argument of read_html(). html_encoding_guess() replaces the deprecated guess_encoding().

Usage

html_encoding_guess(x)

Arguments

x

A character vector.

Examples

# A file with bad encoding included in the package
path <- system.file("html-ex", "bad-encoding.html", package = "rvest")
x <- read_html(path)
x %>% html_elements("p") %>% html_text()
#> [1] "Émigré cause célèbre déjà vu."

html_encoding_guess(x)

# Two valid encodings, only one of which is correct
read_html(path, encoding = "ISO-8859-1") %>% html_elements("p") %>% html_text()

read_html(path, encoding = "ISO-8859-2") %>% html_elements("p") %>% html_text()
