store utf-8 characters to be readable as text too

When you use json.dump(data, f), the data could be ready by json.load(f). But if you want to be able to also read the data using text editors, you should care of the utf-8 chars.

To ensure proper handling of German characters as an example with umlauts (ä, ö, ü), you need to specify the encoding during the dumping process. Here's how:

1. Use the ensure_ascii=False argument:

import json

data = {"Nachricht": "Hallo Welt!"}  # German message

with open("data.json", "w", encoding="utf-8") as f:
  json.dump(data, f, ensure_ascii=False)

In this example:

• ensure_ascii=False tells json.dump not to restrict the output to ASCII characters.
• encoding="utf-8" specifies the encoding used to represent the text. UTF-8 is the standard encoding for handling characters from various languages, including German.

Important:

• Make sure the file you're writing to (data.json in this case) is also opened with the same encoding ("utf-8").
• Your system locale settings might affect how text is interpreted. If you encounter issues, consider setting your locale to German using tools like locale on Linux/macOS.
