Data Grid Header

is there a way to display a 'ß' in the header of the columns?
Example: 'Straße' is always displayed in 'Strasse'
And the second question would be, if you can make the headers easy copyable?
Thank you for your help!

It will display whatever you set as Title:

Well I looked it up and I do it exactly the same way as you shown in your pictures but it is still converting a 'ß' in 'ss'
