Removing characters from questions uploaded to a SharePoint list

Chris_Clark1968 in your flow in Power Automate that creates the list item you just need to add a couple of Compose actions. In this example form there is one multi select question for the engineer(s) who performed a car service.

In your flow, the expression in the first compose is json( then you select the question about the engineer and the expression looks like this
json(outputs('Get_response_details')?['body/re5b63d5a2fe441fd8b650fb66c22fc7d'])

The expression for the second compose is join( then you select the outputs of the previous compose and add a ,' , ' 
join(outputs('Compose-Convert_Engineer_to_JSON'),', ')
 

Then in the create item action, for the engineer column the outputs of the second compose have been selected from the dynamic content box.

The first item in the list below didn't have the compose actions. The second one did and you'll see it's stripped out the special characters.
