I've found out the problem page and output a "error_sample.key" file, and do you need it?

[Erimus-Koo]

The problems happened while some objects used(and error key):

• 6383: table
• 10000: 2d donut chart

[Erimus-Koo]

And there's another problem is, after once used the "replace" command, it looks like a codec error occurred.
Here is the console:

    _file.filename = _file.filename.encode("cp437").decode("utf-8")
  File "/Users/erimus/.pyenv/versions/3.10.9/lib/python3.10/encodings/cp437.py", line 12, in encode
    return codecs.charmap_encode(input,errors,encoding_map)
UnicodeEncodeError: 'charmap' codec can't encode characters in position 10-16: character maps to <undefined>

• Before using the "replace" command, unpack did work.
• The first time use "replace", success.
• And use "replace" or "unpack" again, above error occurred.
• It happens while the image name contains Chinese characters.

I am also seeing the error when parsing the identifier 6383, which appears to be the result of having a table in the file. Python 3.8.2, keynote-parser v1.12.2.0, Keynote v12.2.1.

Example .key file generating the error is attached (attached in .zip format because Github is cranky about .key files).

I fixed the issues I was having by making a few modifications to codec.py and mapping.py. See https://github.com/psobot/keynote-parser/pull/48/files.
