Instructions for Finding Special Characters
If you receive an error such as "Unrecognized character" or "Invalid character" the sql script likely contains non-UTF characters which need to be removed from the sql script.
Open the file in Notepad++.
In the lower right of the screen you can find the file encoding.
To find non UTF-8 in Notepad++ go to Encoding → Encode in UTF-8. The setting should highlight the special characters.
In the screenshot above the xA0 represents non UTF-8 characters that will throw errors when the script is passed to sqlcmd, sqlplus, and other utilities. Those characters will need to be deleted from the feed.
Additional if you want Notepad++ to move the cursor to non UTF-8 characters for easier removal, go to Search → Find characters in range…
Select Non-ASCII Characters (128-255)
Use ‘Find’ button to move the cursor to the special characters.
