Having error when trying to get details from pdf page generated with html emoji code inside pdf text

[luffyfr]

• PHP Version: 8.1
• PDFParser Version: 2.9.0

Description:

When trying to call $currentpage->getDetails(); with a pdf contains an emoji html code, I have this error :
Object of class Smalot\PdfParser\Header could not be converted to string
it's happening in Font.php file, when function getName return "[Unknown]";

Code

I fix this error replacing the code by :
$details['Encoding'] = $this->getName() != "[Unknown]" ? ($this->has('Encoding') ? (string) $this->get('Encoding') : 'Ansi') : 'Ansi';

Is that possible to check this,
Best Regards.

I don't get any error, but I also get a string of six invalid bytes rather than an emoji.

The document stream is printing character at code point 76 from font F6, but it's not being interpreted as an emoji.

Probably some kind of font decoding issue.
