Summary: parse_url corrupts some UTF-8 strings
Status: Open

Package: URL related

New Comment:
On our Debian 4.3.2-1.1 server, changing the locale from LANG=en_US to
LANG=en_US.UTF-8 seems to have fixed this problem.
In my opinion, parse_url() should treat all extended characters (octets 80-FF)
as
opaque characters and copy them as-is without modification. Then, the
function
will work fine for both utf-8 and iso-8859-1 strings. The behaviour of
parse_url() should not depend on the LANG setting. In my opinion, this
function
is buggy.

This issue seems to be platform dependent. For example, on Windows Vista with
PHP 5.3.1, parse_url('http://mydomain.com/path/é') returns $array['path'] =
"/path/". However, on a MAC, it works correctly and returns "/path/é".
We can work around it by uuencoding each part of the array and then decoding
the various legal URL characters ("/", ":", "&", and so on) before running
parse_url, then decoding the path. However, a parse_url_utf8 function would be
very convenient and probably faster. Thanks.

The problem is that nothing guarantees a percent-encoded URL should be
interpreted as containing UTF-8 data or that an (invalid) URL containing
non-encoded unreserved characters should be converted to UTF-8 before being
percent-encoded.
In fact, while most browsers will use UTF-8 to build URLs entered in the
address bar, in case of HTML anchors in HTML pages, they will prefer to use the
encoding of the page instead if it's also an ASCII superset.
That said, the corruption you describe seems uncalled for. In fact, I am unable
to reproduce it. This is the value of $url I get in the end:
string(32) "/he/פר××ק×××/ByYear.html"

I tend to agree with Pajoye.
Although RFC-3986 calls for the use of percent-encoding for URLs, I believe
that it also mentions the IDN format (and the way things look today, there is a
host of websites that use UTF-8 encoding, which benefits the readability of
internationalized urls).
I admit not being an expert in URL encoding, but it seems to me that corrupting
a string, even if it does not meet the current standards, is a bad habit.
In addition, utf-8 encoded URLs seem to be quite common on reality. Take the
international versions of Wikipedia as an example.
If I'm wrong about that, I would be more than happy to know it.
I am not sure that the encode-analyze-merge-decode procedure is really the best
choice. Perhaps the streamlined alternative should be considered. It sure
wouldn't hurt.
I, for one, am currently using 'ASCII-only' URLs.

It is not a bogus request. The idea would also to get the decoded (to UTF-8)
URL elements as result. It is also a good complement to IDN support

I'd say this request/bug is bogus because such URL is not valid according to
RFC 3986. He should first percent-encode all the characters that are unreserved
(perhaps after doing some unicode normalization) and only then parse the URL.
