Simply

pip install polishify

If you have some text that is in Polish but characters look weird it might not be encoded with windows-1250 or iso-8859-2 encoding. If your file is sometext.txt you may

polishify sometext.txt

and it will show you something like

detected encoding is:  windows-1250

If you wish to get this file converted to utf-8 just do

polishify sometext.txt properly-encoded.txt

If you do it in bash script you might not want to see any outputs, the script supports silent mode as follows

polishify sometext.txt properly-encoded.txt --silent

This package contains words with polish letters, you might want to use your own dataset dataset.json file.

polishify sometext.txt properly-encoded.txt --silent --dataset dataset.json

We also provide a tool that generates it from a text

polishify-extract sometext.txt dataset.json --encoding windows-1250
