    @Shambhu Rai - Thanks for the question and using MS Q&A platform.

    It sounds like you are experiencing an issue with square boxes appearing in your Databricks notebook when trying to read a CSV file that contains a wildcard character in a column. This issue may be related to the encoding of the CSV file.

    To resolve this issue, you can try specifying the encoding of the CSV file explicitly when reading it into Databricks. You can do this by setting the encoding parameter of the read function to the appropriate encoding for your CSV file. For example, if your CSV file is encoded in UTF-8, you can specify the encoding as follows:

    df = spark.read.format("csv").option("header", "true").option("encoding", "UTF-8").load("path/to/csv/file.csv")
    

    If this does not resolve the issue, you can try opening the CSV file in a text editor that supports the encoding of the file and replacing the wildcard character with a different character that does not cause issues. Once you have replaced the wildcard character, you can save the file and try reading it into Databricks again.

    If you are still experiencing issues, please provide more details about the specific error message or behavior you are seeing in Databricks so that I can provide more targeted assistance.

    Hope this helps. Do let us know if you any further queries.
