c# - Paste Filepath via White UI \ is printed as ß

Question

I am working on a White UI automatisation program.

My current step in the automation process is to "paste" a systempath to a file I want to open.

mainWindow.Keyboard.Enter("C:\\Folder\\File.jpg");

Pastes this String to the GUI but instead of \ it prints a ß

same when using

\u005c as enconding for \\

There must be some kind of enconding error. System where program is executed operates Win 7 32bit.

Quickfix

The Quickfix for this problem is to take US as standard keyboard layout. Since there seems to be a problem with the White UI Keyboard.Enter(String) implementation regarding special chars in other languages.
