Hello List,
I have a problem with the php CURL module and UTF-8 data.
My php script uses curl to do a post to a perl/cgi script. This perl script
returns UTF-8 encoded XML. The perl script returns utf-8, i have verified
that using the webserver logfiles, but the data that i receive in $result
(see below) is decoded to ISO-8859-1.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $post_url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_VERBOSE, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
$result = curl_exec ($ch);// #### UTF compatible?
curl_close ($ch);
I did some further testing, and i found that this behaviour is not
consistent. Actually i am pretty puzzled about this.
I was testing with a xml document that
contained only the following multi byte utf chacracter:
\303\253 (octal utf8) (LATIN SMALL LETTER E WITH DIAERESIS)
The output from CURL got automatically decoded to latin1.
Then after that i tested with another xml document that
contained the following multi byte utf character:
\342\202\254 (octal utf8) (EURO SIGN)
I was suprised to see that the output was now correct UTF-8.
Now i modified the first document and inserted the EURO SIGN in this
document. When i process this document again, the CURL output is UTF-8. So
it seems the output of CURL depends on what it detects on its imput, and it
will try to convert the data to latin1 if possible??
Does anyone know how i can disable this behaviour? For me, CURL should not
do any en/de-coding of my data.
I also looked around at the cURL library site (http://curl.haxx.se/) of the
developer of CURL. In message
http://curl.haxx.se/mail/curlphp-2001-02/0005.html the cURL developer
indicates that the libraries do not care about character sets, and that it
might have something to do with the implementation into PHP.
If this is true, then theres probably not much i can do about it. If its the
case, please let me know, so i can find an alternative.
Greetings,
