findHTTPHeaderEncoding {RCurl} | R Documentation

## 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.
