The problem is here: http://lxr.php.net/opengrok/xref/PHP_5_4/Zend/zend_exceptions.c#391
Dunno what to do in this case: either add to the docs that the result of getTraceAsString() is
perfectly safe from binary symbols or drop that code completely and allow any chars there.

It's UTF8 already.

Nevermind, I see the problem.

What if you try to switch your browser encoding to UTF8 from whatever it is by default?

Description:
------------
Exception::getTraceAsString, Exception::__toString are not able to properly handle unicode in stack
trace. Instead of showing actual argument values it's giving ???? in case value is unicode.

Tested on PHP 5.3 and PHP 5.4.

Test script:
---------------
<?php
function test($arg){
	throw new Exception();
}

try {
	test('тест');
}
catch(Exception $e) {
	echo $e->getTraceAsString();
	echo (string)$e;
}

Expected result:
----------------
d:\web\usr\local\php54>php.exe d:\src\exception_wrong_trace\test.php
#0 D:\src\exception_wrong_trace\test.php(7): test('тест')
#1 {main}exception 'Exception' in D:\src\exception_wrong_trace\test.php:3
Stack trace:
#0 D:\src\exception_wrong_trace\test.php(7): test('тест')
#1 {main}

Actual result:
--------------
d:\web\usr\local\php54>php.exe d:\src\exception_wrong_trace\test.php
#0 D:\src\exception_wrong_trace\test.php(7): test('????')
#1 {main}exception 'Exception' in D:\src\exception_wrong_trace\test.php:3
Stack trace:
#0 D:\src\exception_wrong_trace\test.php(7): test('????')
#1 {main}
