findHTTPHeaderEncoding {RCurl}

Find the encoding of the HTTP response from the HTTP header

Description

This function is currently made available so it can be called from C code to find the charset from the HTTP header in the response from an HTTP server. It maps this charset value to one of the known R encodings (UTF-8 or LATIN1) or returns the native encoding.

This will most likely be removed in the future.

Usage

findHTTPHeaderEncoding(str)

Arguments

str

one or more lines from the HTTP header

Value

NA or an integer value indicating the encoding to be used. This integer corresponds to the cetype_t enumeration in Rinternals.h.
