undetected possible encoding issue

[eloiup]

Hi

was doing a callback to filter a dataframe through a categorical variable.

Categorical value had accentuation (portuguese)

When filtering it through:
`
@app.callback...

def filter_function(input_variable):

    df_2 = df.loc[df['series'].map(lambda x: x in input_variable)] ##input_variable is a list of strings

    return some_value_function_of_d2

`

it didnt give any error msgs, but numbers werent checking out. after some time looking into it i noticed what was happening is that the filter wasnt working properly for one of the strings in the list, the one with accentuation, most likely an issue with encoding.

if necessary i can provide further detail
