-// 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....
