Reading data error

Description

For reading data from MSSQL, there was one record with bad data, and it threw an error with the message below:
Character set conversion is not available between client character set '(null)' and server character set '(null)'

My question is if this is expected behavior - reading your documentation, my understanding is that it is supposed to return data with ? marks.

Please advise, thank you.
