argparse io issue

[snippsat]

The lsdreader dos not work later version of Python.
It's made a long time ago and the Python 3 compatibility they added is not testet good enough on Windows.
To make it work download Python 3.9(do not add to Path),go to Scripts folder and do pip install lingvoreader
Open C:\Python39\Lib\codecs.py line 378 change to this.

self.stream.write(data.decode())  # Add .decode()

Teste that it works.

C:\Python39\Scripts
λ lsdreader --help
usage: lsdreader [-h] (-i INPUT | -a) [--header] [-o OUTDIR] [-c] [-v] [--version]

Decode Lingvo lsd dictionary to dsl

optional arguments:
  -h, --help            show this help message and exit
  -i INPUT, --input INPUT
                        Dictionary to decode
  -a, --all             All dictionary in current directory
  --header              Print dictionary header and exit
  -o OUTDIR, --outdir OUTDIR
                        Output directory
  -c, --codecs          print supported languages and their codes
  -v, --verbose
  --version             show program's version number and exit

Can not use newer version because they have frozen codecs.py into Python(python.exe).
