Sorry if I'm not reading the nuances correctly, but it looks to me
that you failed to realize that string methods return results.  They
don't change the string in place:

Python 3.8.10 (default, Mar 15 2022, 12:22:08)
[GCC 9.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> str1 = "\u2019string with starting smart quote"
>>> str1
'’string with starting smart quote'
>>> new_str = str1.replace("\u2019","'")
>>> str1
'’string with starting smart quote'
>>> new_str
"'string with starting smart quote"
>>> repr(str1)
"'’string with starting smart quote'"
>>> repr(new_str)
'"\'string with starting smart quote"'
>>>

As you can see, str1 doesn't change, but when you 'replace' on it, the
result you want is returned to new_str
