Remove ASCII characters from text data in Data Management (EPBCS)

We are getting "XML Load Error: Invalid Unicode Character" error while refreshing Text data in SmartView for ASO cube as there are ASCII symbols in text data which got loaded using Data Management and source is a Fusion BIP report. HFR report is also throwing error. It only works Data Forms but with “􀀶” symbol.

We need to remove these characters while loading this data in ASO cube.

Please let me know if there is a way to handle/remove all ASCII symbols which are not recognized in Data Management or if there is any other solution to handle this issue.
