should reserved characters be encoded? See
Details.
Value
A character string.
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.
