#44945 [Bgs]: escapeshellarg removes UTF-8 multi-byte characters

ID: 44945 User updated by: thomas dot jarosch at intra2net dot com Reported By: thomas dot jarosch at intra2net dot com Status: Bogus Bug Type: Strings related Operating System: Linux PHP Version: 5.2.6 New Comment: Thanks for looking into this, Jani. So, why does it work via CLI and not via apache if the same LANG environment variable is specified? I've even seen an "AddDefaultCharset UTF8" entry in the apache config. Thomas Previous Comments: ------------------------------------------------------------------------ [2008-07-13 17:01:20] jani@php.net There's no automatic way. If you need to have it work with utf-8 of course you have to set the locales properly too. Or just not use UTF-8.. ------------------------------------------------------------------------ [2008-05-08 12:59:36] thomas dot jarosch at intra2net dot com Thanks, that seems to work. I've inspected the environment on the server and it contains a LANG="en_US.UTF-8" variable. Is there a way I can fix this/PHP autodetects it without touching every code using escapeshellarg()? ------------------------------------------------------------------------ [2008-05-08 11:28:25] felipe@php.net Try with the code below (mandatory in the test): if (false == setlocale(LC_CTYPE, "UTF8", "en_US.UTF-8")) { die("skip setlocale() failed\n"); } ------------------------------------------------------------------------ [2008-05-08 11:08:27] thomas dot jarosch at intra2net dot com Description: ------------ Hello together, I'm seeing almost the same issue as #44564 after upgrading from PHP 5.2.5 to 5.2.6. If I execute the provided test code via php CLI, everything works as expected. Running the same code via mod_php inside Apache skips the UTF-8 multi-byte characters. I've looked at the ext/standard/exec.c code a bit and checked that my "config.log" in both PHP build directories contains "#define HAVE_MBLEN 1" so the call to php_mblen() should work. Any idea what that could be? One thing I noticed is that php_mblen() is a wrapper macro for mblen() or mbrlen() which features a slight difference in the return code (see -2 rc for details). Thanks, Thomas Reproduce code: --------------- var_dump(escapeshellarg('ä')); Expected result: ---------------- string(2) "'ä'" Actual result: -------------- string(2) "''" ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44945&edit=1
