Special Unicode characters causing exception for GraphQL when used for backing columns

If the configuration file contains backing columns with unique Unicode characters within them (ie: outside of the normal range of [A-z] and [a-z]), we will get errors during bootstrapping for GraphQL. This causes the GraphQL service to fail to run, and be unavailable. REST will still function as normally.

This needs to be investigated, and appropriately mitigated.

Setting to November Milestone to prioritize less niche bugfixes first.

backing columns names comes into play when mapping i.e. aliasing feature is supported for GraphQL. We haven't added/tested that feature yet for GraphQL so moving this to Mar2023.
