The Unicode replacement character � (often a black diamond with a question mark in it) will often appear when imported data is invalid.

Here is a smart list you can setup and subscribe to be alerted of an issue with a list import.

In this example, I created the smart list in my master data management program.

Smart List - Unicode Replacement Character- List Import (Created in past 24 hours): Set the subscription to this list.

In this case I sent the date of activity for the past 24 hours but you can customize the time frame.

Now you can trouble shoot issues more quickly.
