WideCharToMultiByte not respecting regional settings?

[jbirch]

This was just reported on the mailing list:

 I found finally what the problem is and the solution.
 
 Exception was raised when trying to set the scale bar in the print layout.
 
 It's all about Regional Settings. My computer has default French regional settings applied and the group symbol is set to blank. So, a scale number like 98765 is converted as 98 765. Because of this MgUtil.WideCharToMultiByte try to do conversion and fails.
 
 Changing this parameter (set ',' instead of blank) allows print correctly.

I get the same error in Version 1.2.0.1704 on a Swedish OS, but I can't fix it by changing the group separator into ','. The only thing that makes it possible for me to use printlayouts is to disable the scale bar.

Error: Invalid argument(s):

[1] = "const string&"

The string is invalid and cannot be converted.
