[TYPO3-50-general] corrupted chars in DebugExceptionHandler

[Steffen Kamper]

Hi,

as we use a backported error- and exceptionhandler in v4, i stumbled 
about corrupted chars in DebugExceptionHandler::getBacktraceCode

$preparedArgument = (strlen($argument) < 80) ? $argument : 
substr($argument, 0, 40) . '…' . substr($argument, -40);
$preparedArgument = htmlspecialchars($preparedArgument);
$preparedArgument = str_replace("\n", '<span 
style="color:white;">�</span>', $preparedArgument);
$arguments .= '"<span style="color:#FF8700;">' . $preparedArgument . 
'</span>"';

It's corrupted in FLOW3 as well.

Any suggestion for correcting?
