Bug #51947 [Opn->Bgs]: json_encode fails to decode non-breaking spaces

Edit report at http://bugs.php.net/bug.php?id=51947&edit=1 ID: 51947 Updated by: aharvey@php.net Reported by: ehsan dot akhgari at gmail dot com Summary: json_encode fails to decode non-breaking spaces -Status: Open +Status: Bogus Type: Bug Package: JSON related Operating System: Windows, Linux PHP Version: 5.3.2 New Comment: This is expected behaviour: as Arpad says, json_encode() expects input to be encoded in UTF-8. json_encode(utf8_encode(chr(160))) behaves as you'd expect: you get "\u00a0" as the result. Previous Comments: ------------------------------------------------------------------------ [2010-05-29 09:46:28] arpad dot borsos at googlemail dot com I have an outdated 5.2.4 on my server which returns an empty string instead of null in that case. Anyway, 0xa0 (160) is not a valid utf8 character (it needs to be 0xc2 0xa0) and thus invalid json. I believe PHP is right about erroring out in this case. var_dump(json_encode(utf8_encode(chr(0xa0)))); and $encutf8 = json_encode(chr(0xc2).chr(0xa0)); var_dump($encutf8); both work fine. Can you check the output of json_last_error() please? ------------------------------------------------------------------------ [2010-05-29 01:24:00] ehsan dot akhgari at gmail dot com Description: ------------ I've seen that json_encode cannot encode a non-breaking space character, and returns "null". I've reproduced this on php5.3.2 on Windows and Linux. Test script: --------------- <?php var_dump(json_encode(chr(160))); ?> Expected result: ---------------- string(3) "" "" Actual result: -------------- string(4) "null" ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=51947&edit=1
