Thanks for tackling this. Because it addresses a critical data reliability area, we want to make sure it has excellent test coverage. Could you please add some tests?

Also, the original issue mentions issues with deserializing existing corrupted projects, which this doesn't seem to address.

p.s. because this is likely a much bigger task than you anticipated, you are welcome to switch to a more manageable sized task, if that's your preference.

Thanks for additional updates. I apologize for not noticing before that this PR was created from your master branch, but that's going to be very susceptible to inadvertent changes. Could you please move these to a feature branch and open a new PR based on that?

You can do that by something along the lines of

git remote update
git checkout master
git checkout -b 7341-column-name-escape

to create the new branch and then commit your changes to that, perhaps by using git cherry-pick (although you might want to use git rebase -i to squash some of the commits together so that you have fewer commits to cherry pick.

I will start my review in parallel with that process.
