What extended ASCII character set uses 0x9D?

[John Nagle]

     I'm cleaning up some data which has text description fields from
multiple sources. Some are are in UTF-8. Some are in WINDOWS-1252.
And some are in some other character set. So I have to examine and
sanity check each field in a database dump, deciding which character
set best represents what's there.

    Here's a hard case:

  g1 = bytearray(b'\\"Perfect Gift Idea\\"\x9d Each time')

  g1.decode("utf8")
    UnicodeDecodeError: 'utf-8' codec can't decode byte 0x9d in position 
21: invalid start byte

   g1.decode("windows-1252")
UnicodeDecodeError: 'charmap' codec can't decode byte 0x9d in position 
21: character maps to <undefined>

0x9d is unmapped in "windows-1252", according to

https://en.wikipedia.org/wiki/Windows-1252

So the Python codec isn't wrong here.

Trying "latin-1"

   g1.decode("latin-1")
  '\\"Perfect Gift Idea\\"\x9d Each time'

That just converts 0x9d in the input to 0x9d in Unicode.
That's "Operating System Command" (the "Windows" key?)
That's clearly wrong; some kind of quote was intended.
Any ideas?
