The _filtered + the removed subsets_ of each language represent the entire data for a given language following global deduplication, which means that you do not have to re-deduplicate it yourself. You can find and adapt our filtering [code here](https://github.com/huggingface/fineweb-2/blob/main/fineweb-2-pipeline.py).
 
-Additionally, we also uploaded data for scripts that the language classifier does not support, without any deduplication or filtering. These are prefixed by `und_`.
