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().

# 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] "\xc9migré cause célèbre déjà vu."
html_encoding_guess(x)
#> encoding language confidence #> 1 ISO-8859-1 fr 0.31 #> 2 ISO-8859-2 ro 0.22 #> 3 UTF-16BE 0.10 #> 4 UTF-16LE 0.10 #> 5 GB18030 zh 0.10 #> 6 Big5 zh 0.10 #> 7 ISO-8859-9 tr 0.06 #> 8 IBM424_rtl he 0.01 #> 9 IBM424_ltr he 0.01
