Environment

Cause

The replacement character is the special character appearing in the cost plan .

The replacement character appears as a black diamond with a white question mark. 
The Unicode standard to represent the replacement character is designated as U+FFFD in the Specials table.
The character is used to replace an unknown or unrepresentable character, which indicate problems when a system is not able to render a stream of data to a correct symbol.

The special or replacement characters were injected or introduced, possibly by copy and paste from spreadsheet to Clarity but there is no conclusive evidence that this occurred or how it occurred.

Example:

Resolution

Review the cost plan details and check for any special or replacement characters injected.
