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().
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)
#> encoding language confidence
#> 1 UTF-8 1.00
#> 2 windows-1252 fr 0.31
#> 3 windows-1250 ro 0.22
#> 4 UTF-16BE 0.10

# Two valid encodings, only one of which is correct
read_html(path, encoding = "ISO-8859-1") %>% html_elements("p") %>% html_text()
#> [1] "Émigré cause célèbre déjà vu."
read_html(path, encoding = "ISO-8859-2") %>% html_elements("p") %>% html_text()
#> [1] "Émigré cause célčbre déjŕ vu."
