Thank you for your detailed bug report.

the function __toString is missing on class Encoding I've created it to return an implode of the object for test and the error stoped

[k00ni]

Can you paste your fix here?

[clicksistema]

I've insert this function to class Encoding:

    public function __toString()
    {
        return implode(',',$this->encoding);
    }

Just to be clear that i didn't check for what this class is used. I just created a function that works and was not founded before. I belive that most times this class is not returned as a object of HEADER class but when HEADER has one object of this class the error occurs Maybe the error is deeper of contest. Why sometimes this class is part of HEADER class?

Hi, I have the same issue. But sadly the fix removes the error not the problem. If you have one rouge character in a file no big deal but some of the files, I need to parse, are almost entirely unreadable.

$%&'%()&&&*
etc.

Despite this, the majority of files are parsed nicely so great work.
