+// particular allow implicit conversion of wxString to either of these classes.

+// allowing implicit conversion to "const char *" and "const wchar_t *".
+//
+// Because a lot of existing code relies on these conversions, this option is
+// disabled by default but can be enabled for your build if you don't care
