Bug description:  escapeshellarg removes UTF-8 multi-byte characters

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('�'));

Expected result:
----------------
string(2) "'�'"

Actual result:
--------------
string(2) "''"
