Debugger does not show umlaut in const char * correctly

1. Open "simple" project from tests\manual\debugger\simple\simple.pro in Creator's repository.
2. Place a breakpoint at BREAK_HERE in testTypeFormats() (line 5370).
3. Let the debugger run into this breakpoint.
   In Locals and Expressions view, you can see the values. In the const char * the debugger does not show the umlaut correctly, whereas in the const char[] it does:

   cs	"aöa"	char [5]
   s	"aöa"	char *

   After switching the display format to "UTF-8 String" s is being being displayed correctly.

String should be displayed correctly and consistently by default.
