 This is true in Unicode build but not in ANSI one. You can still build
even 2.8 in ANSI mode and while this does mean that you won't be able to
handle non-ASCII characters easily, if it's not a problem for you, it's
probably much simpler to just do this than to update your legacy code.

 This is determined solely by the encoding of the original string. If it's
(7 bit) ASCII, you can just use wxString::FromAscii(). If it's an 8 bit
string in current locale, then wxConvCurrent is what you need. If it's in
UTF-8, then you need wxConvUTF8.
