django ValueError: source code string cannot contain null bytes

I want to create an app but I want to use my existing tables so I run inspectdb command on terminal

from django.db import models

class OhrmJobTitle(models.Model):
job_title = models.CharField(max_length=100)
job_description = models.CharField(max_length=400, blank=True, null=True)
note = models.CharField(max_length=400, blank=True, null=True)
is_deleted = models.IntegerField(blank=True, null=True)

class Meta:
    managed = False
    db_table = 'ohrm_job_title'

generated by inspectdb based on my table

I'm getting an error trying to runserver command

below is the traceback if someone is interested

I never tried to use "Database First or Legacy Database" approach before. I dont have anything else right now its just my models.py

I just found out my old models.py uses encoding UTF-8 while the file generated by inspectdb is not, Maybe someone will find this useful
