Possible coding error in some words

[MinionAttack]

Hi, doing some training I've found that some words in the train and test files have ??.

• Train file:

Is this correct or did an error occur when uploading the files?

Regards.

It appears that the words in the train and test files that have "??" are likely data errors or corrupted data. These are likely not actual words in the language and may have been introduced during the data collection or pre-processing stage. It's recommended to remove or correct those characters in the train and test files to prevent the model from learning from these errors.

Thank you for clarifying.
