Python - error! C:\file\example.db is not UTF-8 encoded ipython notebook

The error "C:\file\example.db is not UTF-8 encoded" typically indicates an attempt to open a file in a context where UTF-8 encoding is expected, but the file contains non-UTF-8 encoded content. In this case, it seems like you're trying to open a database file (example.db) using a method that expects a UTF-8 encoded file.

Database files, such as SQLite databases (which typically have a .db extension), are binary files and should not be treated as text files with a specific character encoding. You should use appropriate database tools or libraries to interact with them.

Here are a few recommendations:

  1. Use a Database Library: If you're working with an SQLite database, use a library like sqlite3 in Python to interact with it. Avoid trying to open the file directly as a text file.

    Example:

    import sqlite3 conn = sqlite3.connect('C:/file/example.db') cursor = conn.cursor() # Perform your database operations here conn.close()

  2. Use a Database GUI Tool: If you're just looking to inspect or manipulate the database interactively, consider using a database GUI tool like DB Browser for SQLite or SQLiteStudio.

  3. Check Your Code: If you are still encountering issues, review the specific code where the error occurs. Ensure that you are not trying to treat the database file as a text file and that you're using the appropriate methods for working with databases.
