Encodes/decodes strings using URI encoding/decoding in the same way that web
browsers do. The precise behaviors of these functions can be found at
developer.mozilla.org:
encodeURI,
encodeURIComponent,
decodeURI,
decodeURIComponent
Intended as a faster replacement for URLencode and
URLdecode.
encodeURI differs from encodeURIComponent in that the former will not encode
reserved characters: ;,/?:@&=+$
decodeURI differs from decodeURIComponent in that it will refuse to decode
encoded sequences that decode to a reserved character. (If in doubt, use
decodeURIComponent.)
The only way these functions differ from web browsers is in the encoding of
non-ASCII characters. All non-ASCII characters will be escaped byte-by-byte.
If conformant non-ASCII behavior is important, ensure that your input vector
is UTF-8 encoded before calling encodeURI or encodeURIComponent.
Value
Encoded or decoded character vector of the same length as the
input value.
