Description:
------------
urldecode() does not understand the %uxxxx format for escaping unicode
characters above 0xFF.
This is a very old bug, originally reported as bug #15027 and declared
bogus, I believe erroneously, and here is the reasoning...
In all modern browsers (including Mozilla), JavaScript's escape()
function uses %HH for Unicode codepoints below 0x0100, but %uHHHH for
codepoints above there.
>From ECMA-262:
--------------
For characters whose Unicode encoding is 0xFF or less, a two-digit
escape sequence of the form %xx is used in accordance with RFC1738. For
characters whose Unicode encoding is greater than 0xFF, a four-digit
escape sequence of the form %uxxxx is used.
--------------
I believe this is a bug, PHP is unable to urldecode the valid escape()d
values from modern browsers when those escape()d strings contain unicode
characters greater than 0xFF.
Declaring it not a bug because it is not in the RFCs, but rather
defined by ECMA is a poor decision.
Reproduce code:
---------------
echo urldecode('%u2013');
Expected result:
----------------
A string containing the three characters comprising the unicode
character 0x2013 (En Dash) in utf-8, namely 0xE2 0x80 and 0x93.
Actual result:
--------------
The literal string "%u2013".
