Я использую pdfminer для перевода pdf в текст, но некоторые цифры или слова или '[' не могут отображаться 

import sys
import importlib
importlib.reload(sys)

from pdfminer.pdfparser import PDFParser,PDFDocument
from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.converter import PDFPageAggregator
from pdfminer.layout import LTTextBoxHorizontal,LAParams
from pdfminer.pdfinterp import PDFTextExtractionNotAllowed

path = r'C:\\Users\\User\\Desktop\\2002\\1999-66.pdf'
def parse():
    fp = open(path, 'rb')
    praser = PDFParser(fp)
    doc = PDFDocument()
    praser.set_document(doc)
    doc.set_parser(praser)
    doc.initialize()
    if not doc.is_extractable:
        raise PDFTextExtractionNotAllowed
    else:
        rsrcmgr = PDFResourceManager()
        laparams = LAParams()
        device = PDFPageAggregator(rsrcmgr, laparams=laparams)
        interpreter = PDFPageInterpreter(rsrcmgr, device)
        for page in doc.get_pages():
            interpreter.process_page(page)
            layout = device.get_result()
            for x in layout:
                if (isinstance(x, LTTextBoxHorizontal)):
                    with open(r'C:/Users/User/Desktop/2002/3.txt', 'a') as f:
                        results = x.get_text()
                        print(results)
                        f.write(results)

if __name__ == '__main__':
    parse()

Я ожидаю, что результат будет
