Problems when displaying a PDF from binary data

[Werewolve]

Hello, I try to display a PDF file from binary data. I get the error that my file structure isn't correct. Any suggestions how to format the data in the right format? I've tried several different ways: blob, binary array, base64 string... The data looks like that:

`%PDF-1.7 %����

2 0 obj << /Filter /FlateDecode /Length 7719
