Remove "?" from result of query ran on knime

When i run my DB query on knime to fetch data from teradata, it is showing “?” in one of the rows after exporting this data to excel. But when i see this data on teradata it shows as “|”.
How can i remove this character from my data as its causing issue.


@rds how does the character show up in KNIME and have you tried replacing it with a null value?
