I thought that a URL encoded string should convert
the space character to %20 (hex).

curl_escape() converts the space character to a "+".

Also, curl_unescape() does not return the original string:

original, operation=name=abcd efg&value=5
curl_escape(), operation=name%3Dabcd+efg%26value%3D5
curl_unescape(), operation=name=abcd+efg&value=5

The original space was converted to a plus sign,
but did not convert back to a space.

I think the URL encoded string should be:
operation: name%3Dabcd%20efg%26value%3D5
where space is %20.

I also think that curl_unescape() should return
the original string.

RFC 1738, Uniform Resource Locators (URL), mentions
using %20 in place of the space character.

RFC 2316 is mentioned in escape.c, but this rfc
is about Report of the IAB Security Architecture Workshop.

Any thoughts on this appreciated.
