How can I replace double quotes from a Github Context value

I have a Workflow that can be triggered by some issues.
I am using Github context information in my yml file, in particular:

${{ github.event.issue.body }}

I am having an issue with parsing double quotes that are present in some issues, what’s the best way to replace double quotes with single quotes or remove them completely. I want to replace the double quotes in ${{ github.event.issue.body }} store them in another environment variable for further use in other steps.

Thank you.
