Understanding the different types of variable in statistics - Laerd Structural Equation Modeling, 25(3), 359388. In this post, I suggest an alternative statistic based on the idea of mutual information that works for both continuous and categorical variables and which can detect linear and nonlinear relationships. MI has no constant upper-bound though (the upper-bound is related to the entropies of the variables), so you might want to look at one of the normalized versions if that is important to you.

It is a basic idea of measurement theory that such a variable is invariant to relabelling of the categories, so it does not make sense to use the numerical labelling of the categories in any measure of the relationship between another variable (e.g., 'correlation'). It is not really clear what does author of the post you refer to means and how does the answer refer to correlation with categorical data.
