Update:This code has been finalized and debugged, and is now shipped as part ofMagpieRSS 0.7! Sadness and rage no more!

So I have this little program, calledFeed on Feeds. It’s an RSS and Atom aggregator. For a long time I’ve known that it doesn’t quite handle international characters that well, so I set out to fix it. I knew that somewhere between input feed and output HTML page, characters were getting messed up. I adopted a policy of “UTF-8 Everywhere”: since FoF has to deal with feeds in lots of different charsets, but display them all on one page, I’d translate everything into UTF-8. I UTF-ized everything in the display code, and made sure that the DB wasn’t mucking with the characters, finally closing in on the place where it seemed characters were being munged: the XML parser itself, called byMagpieRSS, the RSS and Atom parser used by FoF.

se;ns$`:A6?gPq0Here’s how Magpie was creating the XML parser:木铎校园 BBS 社区 Sl6BqIM6K3vOo

木铎校园 BBS 社区X*}3x_ j1@

$parser = xml_parser_create();木铎校园 BBS 社区s N{uJTdd!{"p m

HP C"~r0Nice! Simple! But it munges characters, especially numeric entities. After reading some PHP docs, I found that there are two things you can set in PHP’s XML parser: the source encoding, and the target encoding. You can set the target encoding this way:

i,Q0["~_(d$`0$parser = xml_parser_create();
.e;H Hs{v2@3W c!\0xml_parser_set_option($parser, XML_OPTION_TARGET_ENCODING, "UTF-8");木铎校园 BBS 社区 lE+cLI

D9@ JGO Y$c0This means: “Whatever charset the XML is in, I want you to translate it into UTF-8. And if you happen to find any numeric entities in there, resolve them into UTF-8 characters, too.”木铎校园 BBS 社区C O
e?PAVK

8f^
Tx)|N7B^-yJ0So I tried that. But it still wasn’t working. Some feeds were translated into UTF-8 properly, but others weren’t. Feeds already in UTF-8 were re-encoded, resulting in gibberish. Reading some moredocumentationandbug reports, I found that if you don’t set the source encoding, PHP assumes your XML is in ISO-8859-1! I was amazed that PHP’s XML parser didn’t examine the XML prolog to determine the encoding, and further shocked that they chose such an insane default. But anyway. You can set both source and target encodings this way:木铎校园 BBS 社区(G_[?]8q

木铎校园 BBS 社区y n i+e!n$S2zi

$parser = xml_parser_create("EBCIDIC");
o C#ZD Y*k;m#P:l*Y0xml_parser_set_option($parser, XML_OPTION_TARGET_ENCODING, "UTF-8");

/ob#C(Qc V0

This means, “I’m about to give you some XML, in EBCIDIC. I want you to translate all those characters into UTF-8 while you’re parsing it. Don’t forget to turn any numeric entities you find into UTF-8, too.”

X$a}2WH2T}0h0That works… but presents a problem. How do you know the charset the XML is in? The only answer I could come up with: scan the XML myself, and find the encoding!

木铎校园 BBS 社区5q _ o(u^!^9H

$rx = '/<?xml.*encoding=['"](.*?)['"].*?>/m';

6R+N|8X6d!v$D9r8M0木铎校园 BBS 社区#Up$a)YGQ2{+h

if (preg_match($rx, $xml, $m)) {木铎校园 BBS 社区Q`2A9?SV2C:D

} else {
R1JRa9N-{(d0  $encoding = "UTF-8";
l'\K {*c0p9E:M0}木铎校园 BBS 社区^/g` z7[c r3ZV

That regex finds the charset declaration in the XML prolog itself, and if found, saves it in the variable $encoding. If it wasn’t found, it assumes the XML is in UTF-8 already, which is the default for XML.

blc?gg(U0So the full code is now:

m.DK0That, finally, worked. All my feeds were reliably translated into UTF-8. But that was just by coincidence. All the feeds I subscribe to were already in UTF-8 or ISO-8859-1. After making this release, people complained that feeds in ISO-8859-15 and BIG-5 weren’t working. Consulting the PHP docs again, and double checking in the source code because it was just so surprising I found that PHP 4.x only supports UTF-8, ISO-8859-1, and US-ASCII. So anybody out there who wants to subscribe to a feed in ISO-8859-anything-but-1 or BIG5 of SHIFT-JIS is still screwed.

Even PHP 5 won’t help here, when it is released: Itsort-ofsupports a longer list of encodings, but not BIG5 or GB2312, the two main Chinese encodings.

So I searched the PHP docs some more, and came up with a potential solution:mbstring! The mbstring family of functions supports a huge long list of encodings, and can translate between them. So here’s the final solution: use a regex to find the source encoding. If PHP can handle it natively, fine. If not, lop off the XML prolog, replace it with one that saysencoding="utf-8"and pass the whole XML file through mb_convert_encoding to convert it to UTF-8 before the parser even sees it. If mb_convert_encoding blows up (which it will if the source encoding is not recognized, or if the function completely doesn’t exist, which I’m told is highly probable, since it is an optional extension) just give up and pass the XML straight to the parser and avert your eyes as it makes mincemeat of the characters. At least I tried.木铎校园 BBS 社区s`]F*U

Surprisingly, this hack on top of a hack wrapped up in a hack with extra hack on top… worked! It was able to parse ISO-8859-15, BIG-5, even GB2312 feeds just fine, and translate them all into UTF-8 for display on a single page. I have these changes in my local copy of FoF now, and I’m going to let them burn in for a few days before I release them to the wider world, who will probably point out, within minutes, the multiple and tragic ways that even this solution fails. But until then, I proclaim that this is the state of the art in PHP XML charset-aware parsing. I think this is as good as it gets in PHP 4.x.木铎校园 BBS 社区 e0w#]b,t

Footnote: when I say PHP5 sort-of supports more encodings, this is what I mean: PHP5 (I looked at RC3, maybe these bugs will be fixed by the final release) is completely nuts. The XML parser supports a bunch more encodings, but they are really hard to get to. If you try to explicitly set the input encoding, the PHP code limits you to UTF-8, ISO-8859-1, or US-ASCII, even though libxml2, the underlying parser, supports many more. But, if you know the super secret codes, you can construct the parser this way:

Cmgl4]2xHE#\!z0$parser = xml_parser_create("");

,N)mOFx(Y^d0

Notice the difference? In PHP5 bizarro world, passing in an empty string means “do what you should have done all along, auto detect the stupid encoding!” But, there’s another problem: if you auto-detect the stupid encoding this way, the stupid target encoding is stupidly set to ISO-8859-1. I don’t know who would want that. And it goes against the documentation, which says by default the target encoding is set to the source encoding. And again, you are restricted artifically from setting the output encoding to anything other than UTF-8, ISO-8859-1, or US-ASCII. So you could, if you want, use a regex (yuck!) to find the source encoding, but you wouldn’t be allowed to set the target encoding to match. But, at least, you can do this:木铎校园 BBS 社区6ET#]v
she(a

+BP?SOc5T0$parser = xml_parser_create("");木铎校园 BBS 社区l9H~jA,Vo0OR
xml_parser_set_option($parser, XML_OPTION_TARGET_ENCODING, "UTF-8");

B{!fF6@5le j0

Meaning, “Auto detect the source encoding, and then translate everything, including numeric entities, into UTF-8.”

*Fq-f\v0At least you will be able to… when PHP5 comes out, and is installed on the server where your application needs to run, which for me (I get complaints that FoF won’t work on PHP 3) probably won’t be for several years.木铎校园 BBS 社区:Rc+Ni.{:[0vd

3pQR$na aW0If you really want to cover all the bases, don’t just look for mb_convert_encoding(): you can also look for (and rarely find) iconv() and recode(). Then, on *nix, try to shell_exec(’iconv…’), though you’ll fail in safe mode and most shared hosts disable shell_exec. But, there’s still one last hope! Most of them don’t realize that they should also disable the strange and terrible proc_open(), so you can actually fork a process to run iconv, and open input and output pipes to feed and read.木铎校园 BBS 社区"KoM d W-CAW0v

Or, sigh, write ten lines of Python to call Mark’s Universal Feed Parser and return the output as a PHP include. Sometimes, PHP really ticks me off.

OOooooo… I didn’t know about those!木铎校园 BBS 社区ISKG6D

Or I could just create a web service:http://xml-transcoder.com/?to=utf-8&url=http://nasty.feed/in/EBCIDIC/or/some/such. Then you’d just seamlessly subscribe to the transcoded version of the feed.木铎校园 BBS 社区J3U}Jr[a_(O

Steve. May you permit me to translate your post into Chinese and share it to the Chinese readers? I consider that there might be lots of people in Asia would like to know how to handle with the International characters while programing PHP.

Yes! You certainly can! If you can wait until Monday, you can post your translation of this article along with a pointer to Feed on Feeds 0.1.7 which will contain the working code.

w2@:`5xi)D)W1r/x0Only one thing, my ISP does not support iconv … my god … How can I do?

*wNLl0jk en0Uh oh… how about ‘mbstring’? If you don’t have iconv or mbstring, then you will only be able to work with feeds that are in UTF-8, ISO-8859-1, or ASCII.

for me it isn’t a good idea to search charset in xml header. it’s good to search in http header because for w3c if charset it isn’t specify in http header you can use xml charset.

:Si.PS4REGg"J0http://www.w3.org/TR/WD-html40-970708/charset.html

To really get it right you have to checkboth. In practice, I haven’t yet found any feeds where checking the headers is necessary or even helpful.木铎校园 BBS 社区R n7N [1YA

possibly, because i’m stupid and know nothing of php encoding.
'S7b0m f2I^0but for all our sakes, go to a party and get hammered.

/v(w]1p*rb'}v0Thomas makes a good point, but it’s even worse than that–not only are there character encodings specified by both HTTP and the XML prolog, but either or both of them could be completely wrong. I would imagine there are many feeds served as ISO-8859-1 that are actually windows-1252 (or whatever it is) and they just don’t happen to contain any of the characters that are different between the two formats, yet. When one of them does, your code might handle it, or maybe it’ll start spitting out gibberish again. And if someone gets UTF-8 and UTF-16 mixed up, I think you could wind up with everything shifted off by a byte, and now the feed is completely unreadable again.

{MmE+k0Basically, until we can convince everyone to use UTF-8/16/32 for everything, this will be a bloody pain in the arse. It looks like PHP just makes it even more painful. I would second Phil’s recommendation: use Mark’s Universal Feed Parser, and when something breaks, just get him to fix it. :-D

#O\1U5K&BP!j0At this point I’m still in the “get it right when the feed is right” stage. FoF still doens’t even do that, all the time. Once I’ve got that one licked, I may move on to “get it right even when the feed doesn’t”.木铎校园 BBS 社区LN6I!ULF yJj

j$_1uyw0] `0Too late probably, but just replace all “” from the string before executing the regexp, and it should work with UTF-16木铎校园 BBS 社区k3S]7Q)E vWM"Q

Cby1q8G-Gmn9c%T0ok, my last comment was “mangled”木铎校园 BBS 社区/mty6a,Hj

Replace all 0-bytes from the string. That’s \ by the way

i suggest to go a little further with the regular expression in a network world full of screwed up source codes:木铎校园 BBS 社区V0Q`VC2TeT

preg_match( “/]+encoding\s*=\s*[’”]?([\w._]+(-[\w._]+)*)[’”]?[^>]\?>/i”, $xml, $m )木铎校园 BBS 社区\Z3|kY(wJ*@

it’s possible i screwed up here myself, double check advised, i didn’t test it yet.木铎校园 BBS 社区?Ss xh:_%d

well seems like your comment page doesn’t translate “smaller than”.

^A} `U,_ r7m0Sorry about that… I think Wordpress probably has a similar screwed up regex that tries to sanitize comments that munged yours.

CqS0J#Pv_%\0Hi, I am using MagpieRSS 0.7 but I still am getting character substitution! please see this site still in progress:

can you tell what could cause this?木铎校园 BBS 社区G#l6ho%`3}o9R h4O

h4Y V@xe)b%uz0Just a note on this bit:

:V aO3A?H0y0“If PHP can handle it natively, fine. If not, lop off the XML prolog, replace it with one that says encoding=”utf-8″ and pass the whole XML file through mb_convert_encoding to convert it to UTF-8 before the parser even sees it.”

It should be noted that any UTF-8 stream can be treated as a valid ISO-8859 stream, since an ISO stream is a series of bytes. However, the reverse does not hold true. There are ISO-8859 (and other single-byte and multibyte streams) that turn out to be invalid as UTF-8 streams.

_[H/b'j~.O:in,R0The reason is that a series of independant bytes is a series of bytes, but UTF-8 has strict rules in which ranges of byte values can follow certain other bytes.

The parser may not fall over now when it hits these invalid sequences, but I am not sure it is safe to assume that will always be the case.

I think it would be safer to send an unknown or unhandlable encoding into the parser as ISO8859, and then convert the entities afterwards. *That* is why the parser defaults to ISO and not UTF.

z1C2`lD{&rj"N8e0Great stuff here. I’m using Magpie v 7a. The parser looks to have I incorporated your encoding fix for PHP4. On my page, particularly in the Yahoo News feeds, several of the characters are converted to question marks. I looked at the original feed, and the special characters are an apostrophe and an mdash. Apparently, all apostrophes aren’t equal as some are handled well and others are converted to ‘?’. The apostrophe causing problems slants backwards (almost like an accent).木铎校园 BBS 社区 ?/XR WjU

All in all, I would say that the output is still pretty good, and completely readable. It would be icing on the cake to fix this problem with special characters.

ohiM(Jyuz0The Yahoo feed is UTF-8. Here is the link to the actual XML file:

"yp;p n}w0link木铎校园 BBS 社区/vd0e.ze&x$AV

Off topic, comparing Yahoo News and Google News feeds. Yahoo is much better in terms of their advanced search options. Google has no provision to exclude based on keywords. However, Google incorporates nice thumbnails into their output descrīptions. This makes them very appealing, and it will be interesting to see how long it lasts before others begin incorporating small thumbnails as well. I could see including a conditional that would only display stories which contained thumbnails.

,f!x;z0MpUY(f8p+_R"JK0I had the same problem using magpie .72 and found that the only solution that worked, was to ditch my UTF-8 feed and replace it with an ISO-8859 feed instead. After changing that setting in WordPress and clearing magpie’s cache, everything worked perfectly.木铎校园 BBS 社区8yS4YhhS'K

Hey all.. Thanks for the post. I am actually trying to mod this plugin right now for my site for something having to do nothing with favicons and would love some help if anyone is willing to trade a few emails.

If you, like me, found no luck here in resolving your char. munging issue in Magpie 0.72 and RSS (Atom works fine, right?) then perhaps what I did may help you…

9Ocal;w0when you include and define your Magpie params be sure to include this line:

define(’MAGPIE_OUTPUT_ENCODING’, ‘UTF-8′);

K5lKsy&O&gS7I#oO0and in the head of your HTML docuemnt be sure (for browser compatability and user preference consideration) to add/change the following:木铎校园 BBS 社区:UY]v~QE

(less than sign) meta http-equiv=”Content-Type” content=”text/html; charset=UTF-8″ / (greater than sign)木铎校园 BBS 社区uh~O6q[Ke k CqoI

of course you will replace the signs indicated in parentesis… without the parenthesis… hehehe
