List of illegal characters

Issue in ./help/sources/tutorials/ui/create/local-system/local-file-upload.md

Customers have run into issues uploading files with illegal characters or column headings.

Can we outline here what characters are considered illegal for both field values and names?

Open help/sources/tutorials/ui/create/local-system/local-file-upload.md and review the existing local file upload guidance. Determine the documented illegal characters for field values and column headings, then add a clear outline to that page. Done means customers can identify which characters are disallowed in names and values.
