The ability for the Rest API to return Facet Options in the correct case as provided by the UI.
Joris checked with your engineering group and this was a design decision they made (because of scalability, performance and some other considerations). So this is considered working as expected and this behavior cannot be configured/controlled right now. He also understood that it might be a significant change to support it.
However, we have certain Text List Items that need to be written in a specific way - an example would be DeWalt (trademarked as DᴇWALT) - We would need to have this written as DeWalt in the facet.
Could it be possible to make this configurable via the rest API, if the user selects to use this then they need to be aware of the performance issues that may come with this.
