I have a CSV file with German words in its entries. Here's an excerpt:
As one can see, a number, a number of entries contain words with German words that contain characters that are depicted somewhat oddly. For instance, in C10 we see a “square root” symbol. Something similar happens in B6 and C5.
Here's the xlsx and the csv files.
Question: how can I change the format of these letters in such a way that the correct (German) characters are depicted? If this is impossible, I would also be content with characters without accents (e.g., O instead of Ö).
