Django's HttpResponse class is most suitable for a text based response (html page, txt file, etc.). The documentation for the class constructor explains:

content should be an iterator or a string. If it’s an iterator, it should return strings, and those strings will be joined together to form the content of the response. If it is not an iterator or a string, it will be converted to a string when accessed.

You UnicodeDecodeError is probably raised when the content is converted to a string. If you want to return a PDF file, the file content is binary data, so it is not intended to be converted to string.

You may use the FileResponse class instead. It inherits from StreamingHttpResponse, and so have a different APi than HttpResponse, but it will probably works better to return a binary file (like a PDF).
