+//
+// This is a copy of intlGUIEditBox from the irrlicht, but with a
+// fix in the OnEvent function, which doesn't allowed input of
+// other keyboard layouts than latin-1
+//
+// Characters like: ä ö ü õ ы й ю я ъ № € ° ...
+//
+// This fix is only needed for linux, because of a bug
+// in the CIrrDeviceLinux.cpp:1014-1015 of the irrlicht
+//
+// Also locale in the programm should not be changed to
+// a "C", "POSIX" or whatever, it should be set to "",
+// or XLookupString will return nothing for the international
+// characters.
+//
+// From the "man setlocale":
+//
+// On startup of the main program, the portable "C" locale
+// is selected as default. A program may be made
+// portable to all locales by calling:
+//
+// setlocale(LC_ALL, "");
+//
+// after program initialization....
