rvest (version 0.3.5)

encoding: Guess and repair faulty character encoding.

Description

These functions help you respond to web pages that declare incorrect encodings. You can use guess_encoding to figure out what the real encoding is (and then supply that to the encoding argument of html), or use repair_encoding to fix character vectors after the fact.

Usage

guess_encoding(x)
repair_encoding(x, from = NULL)

Arguments

x

A character vector.

from

The encoding that the string is actually in. If NULL, guess_encoding will be used.

stringi

These function are wrappers around tools from the fantastic stringi package, so you'll need to make sure to have that installed.

Examples

# NOT RUN {
# 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_nodes("p") %>% html_text()

guess_encoding(x)
# Two valid encodings, only one of which is correct
read_html(path, encoding = "ISO-8859-1") %>% html_nodes("p") %>% html_text()
read_html(path, encoding = "ISO-8859-2") %>% html_nodes("p") %>% html_text()
# }
