wxWidgets has recently changed so that the >= 2.9 version always uses utf8
in the wxString.

There's a list of what it accepts in the section "wxString
<http://docs.wxwidgets.org/3.0/classwx_string.html> can be created from".

What do you plan to do with this wxString? You won't be able to display it
in the GUI since the high ASCII chars usually just show up as boxes not as
the DOS smiley faces and whatnot. I recommend sanitizing the string for
display by replacing the extended ascii and controls chars with '?' for
example.

You can make an ANSI build of wxWidgets (frowned upon in wx versions >=
2.9) and see if that does what you want...
