UnicodeEncodeError: 'charmap' codec can't encode character '\u2264' in position 30: character maps to <undefined>

from timeshap.explainer import global_report
sequence_id_feat = 'id'
time_feat = 'Date'
#pos_dataset = d_test_normalized[d_test_normalized['label'] == 1]
schema = schema = list(trial.columns)

While running the above code, I am getting the following error related to encoding:

Is the issue while writing to the csv or vice versa? I am pretty lost here.

I am also experiencing this global_report issue with recommended dependencies (except downgrade of shap to 0.42.1 due to renaming of explainers: #56). Any progress on this?
