Creating a folder starting with an uppercase Ü displays it with a lowercase ü

I have a folder called "Über uns", and even though it's showing properly in the text field, on the actual page it renders as "über uns", just like when sorting.

It would be nice to be able to differentiate between Name and Link with folders as well.

The issue does not identify a file, test, or entry point. Reproduce the uppercase-Ü folder display in the Grav Admin interface, trace where the folder name is rendered or sorted, and verify that the displayed name preserves its original capitalization while any link behavior remains distinct.
