// 11.11.2011 11:11 ValkaTR
//
// 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....
