Description (last modified by Jacob Walls) 

>>> Author.objects.annotate(first_letter=Chr(Value(77)))
File "/Users/.../.../.venv/lib/python3.9/site-packages/django/db/models/expressions.py", line 369, in <lambda>
    else int(value)
ValueError: invalid literal for int() with base 10: 'M'

I'm suggesting in Chr we can set output_field = CharField() to prevent this.
