python convert unknown character to ascii

In a text file I'm processing, I have characters like ����. Not sure what they are.

I'm wondering how to remove/convert these characters.

I have tried to convert it into ascii by using .encode(‘ascii’,'ignore’). python told me char is not whithin 0,128

I have also tried unicodedata, unicodedata.normalize('NFKD', text).encode('ascii','ignore'), with the same error

Anyone help?

Thanks!

Solution

  • You can always take a Unicode string an use the code you showed:

    my_ascii = my_uni_string.encode('ascii', 'ignore')

    If that gave you an error, then you didn't really have a Unicode string to begin with. If that is true, then you have a byte string instead. You'll need to know what encoding it's using, and you can turn it into a Unicode string with:

    my_uni_string = my_byte_string.decode('utf8')

    (assuming your encoding is UTF-8).

    This split between byte string and Unicode string can be confusing. My presentation, Pragmatic Unicode, or, How Do I Stop The Pain can help you to keep it all straight.
