Python searching through file with obfuscated characters

[Tysoukii]

Doing a few challanges, trying to use Python to solve as much as possible (As I know the challange can be completed without the use of Python). One challange, relating to Steganography, was to find the filename and any extensions within an image. Doing Steg scans with wordlists could resolve this, but somebody mentioned to me that if I opened the image as a word file, then the actual text is visual already.

This is true, but with over 500 lines of this: �~�b���:ӄ��M��Ɖ�� D�B`�"YOU_GOT_IT_RIGHT!"

I wanted to see if there was a way I could implement a Python script to search through the file and then just show me all English characters (with possibly "!","_","{","}"). I mean all ASCII characters; which includes the uppercase and lowercase latin alphabet, numerals, and english special symbols

Any help would be appreciated.

A little mix-match of things I have tried below.

import json
import string


start = json.loads(open('image.json').read())
     
Lower = ("a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y" ,"z")
Upper = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R" , "S", "T", "U", "V", "W", "X", "Y", "Z"]
Special = ["!", "_", "{", "}", "(", ")"]

TEST = string.printable
print (TEST)           

filtered_contents = ''.join(filter(lambda s: s in TEST, start))
myfile.close()

import re
nameoffile = ""
with open(nameoffile,"r") as file:
    data = file.read()

    data = ''.join(i for i in data if ord(i)<128)
    print(data)

this should suffice in theory "re" is defult in windows python installation afaik, ofc instead of data from file any string should do in theory
