Signals Notebook: Error importing CSV file with unrecognized degree character

Users might experience errors while importing CSV files into a table when the file contains temperature characters in an unrecognized format.

There are two errors that can be displayed, the first one can be seen above the import/export menu within the table information item.

The second issue is a question mark displayed in the table for the columns where the character is not recognized.

Solution: the easy way to fix this is replacing the degree symbol with the correct one using ALT-0176. Also this can be avoided if the exported file has the degree symbol in the correct format.
