Answer / Mahavir Singh

The issue you're encountering might be due to a mismatch between the character set or collation of your database and SQL Toad client. To resolve this, follow these steps: 1) Verify that your database's character set and collation are correctly configured to handle both English and Arabic characters. 2) Ensure that SQL Toad is set to use the same character set and collation as your database. This can be done by going to 'Preferences' -> 'Database' -> 'Character Set' in SQL Toad. 3) If none of these solutions work, consider reaching out to the support team for SQL Toad or your database management system for further assistance.
