URLencode {utils}

R Documentation

Encode or Decode a (partial) URL

Description

Functions to encode or decode characters in URLs.

Usage

URLencode(URL, reserved = FALSE)
URLdecode(URL)

Arguments

URL	A character string.
reserved	should reserved characters be encoded? See ‘Details’.

Details

Characters in a URL other than the English alphanumeric characters and ‘⁠$ - _ . + ! * ' ( ) ,⁠’ should be encoded as % plus a two-digit hexadecimal representation, and any single-byte character can be so encoded. (Multi-byte characters are encoded as byte-by-byte.)

In addition, ‘⁠; / ? : @ = &⁠’ are reserved characters, and should be encoded unless used in their reserved sense, which is scheme specific. The default in URLencode is to leave them alone, which is appropriate for ‘⁠file://⁠’ URLs, but probably not for ‘⁠http://⁠’ ones.

Value

A character string.
