Greetings!!
Steps to Fix Special Character Issues When Importing CSV into Azure Data Studio on macOS:
1.Check and Convert the Encoding of Your CSV File
- Open your .csv file in a text editor like VS Code.
 - Look at the bottom-right corner to check the current encoding (e.g., Windows 1252, MacRoman, etc.).
 - If it's not UTF-8, convert it:
 - Go to File → Save with Encoding → UTF-8.
 
2.Save the File as UTF-8 Without BOM
- When saving, choose UTF-8 without BOM.
 - This ensures that special characters (e.g., é, ü, ñ) are preserved correctly and prevents any hidden byte order marks that might interfere with import.
 
3.Re-import the File Using Azure Data Studio
- Open Azure Data Studio.
 - Use the Import Flat File Wizard to load the newly saved UTF-8 file.
 - Special characters should now be imported correctly without showing as ?.
