php see and remove broken symbols from string

Question

based on THIS question.

I am parsing a file with bom and get some strange content that I need to remove (see image below)

I am trying to remove bom, but apparently this is not bom as solutions with bom removing are not working. Also I tried this:

$str = preg_replace('/[\x00-\x08\x0B\x0C\x0E-\x1F\x7F-\x9F]/u', '', trim($str));
$str = preg_replace('/[\x00-\x1F\x7F\xA0]/u', '', trim($str));

So I need to see what this actually is and remove it. This occurs only with the 1st line of file, all other lines do not contain it. Any ideas how to fix it would be welcome. Thank you.

No, I need all valid letters, symbols, arithmetic signs etc, everything that could be correctly showed it chrome dev tools, but this uis actually a tricky issue. So I need to see what that actually is (that red dot) and to remove it. — Jack, Aug 07 '18 at 10:09
You should not look to remove it but to "kill" the source of it so it does not get added in the first place — Marvin Fischer, Aug 07 '18 at 10:14
Or `var_dump(array_map('dechex', array_map('ord', str_split($first_line))))` if you prefer — Chris Lear, Aug 07 '18 at 10:25

You can use this . and get

$str = ".test_id_sbj";

$result= explode('.',$str);

echo $r = $result[1];

It's a 3-character string with no unicode representation, not a `.` – Chris Lear Aug 07 '18 at 10:22
It's not my code, but I can see that the image in the question says `string(14)` – Chris Lear Aug 07 '18 at 10:26
