How to resolve garbled characters when executing an SQL file in db2?

When encountering garbled characters while executing an SQL file in a DB2 database, it could be due to the following reasons:

The file encoding does not match: Please ensure the encoding of the SQL file matches the encoding set in the database. Common encodings include UTF-8, GBK, etc. You can use a text editor (such as Notepad++) to open the SQL file and check the encoding. If the encoding does not match, you can try saving the SQL file in the correct encoding format and then try running it again.

2. Incorrect database parameter configuration: If the character set and sorting rules of the database are incorrect, it can result in garbled text. This issue can be resolved by checking the character set configuration of the database. You can use the following command to view the current character set settings in a db2 database:

   db2 get db cfg for <database-name> | grep -i codeset

If the character set is not configured correctly, you can change the character set and collation by modifying the database configuration file or executing the appropriate ALTER DATABASE statement.

3. Illegal characters may exist in the SQL file: Occasionally, the SQL file may contain special or illegal characters which can result in garbled text. Open the SQL file with a text editor to check for any unusual characters. If necessary, remove these characters and re-run the SQL file.

Command line tools may display issues where certain characters cannot be correctly shown, resulting in garbled text. In such cases, you can try using a different terminal or tool to view the results, such as connecting to the database using a Graphical User Interface (GUI) tool.

If the above solutions do not work for fixing the garbled text issue, I suggest describing the problem in more detail so that I can provide more specific assistance.
