After decoding a GET-request containing %D0%27 an extraneous \ is inserted between the two characters. This may easily reproduced by calling a PHP-page containing phpinfo(), calling it with ?request=%D027 ad taking a look at the "PHP Variables" section.

_GET["request"] ?\'?
_SERVER["REQUEST_METHOD"] GET?
_SERVER["QUERY_STRING"] request=%D0%27?
_SERVER["REQUEST_URI"] /bla.php?request=%D0%27

For your convenience I've added some more lines from the output:

_SERVER["SERVER_SOFTWARE"] Apache/1.3.23 (Unix) mod_ssl/2.8.7 OpenSSL/0.9.6b PHP/4.1.2?

Configure Command?'./configure' '--with-pgsql' '--with-apxs=/usr/local/apache/bin/apxs' '--with-xml' '--without-mysql' '--enable-sysvshm' '--enable-sysvsm' '--with-config-file-path=/usr/local/apache' '--enable-track-vars' '--enable-force-cgi-redirect' '--with-gettext' '--enable-inline-optimization'

I've seen the bug the first time with PHP 4.0.6,then checked against PHP 4.1.2.

Check your php.ini..you have 'magic_quotes_gpc=On' there. Turn it off and you won't see the slash.
Not a bug but expected behaviour.
