Latin2 keyboard input problem

[UBoss UBoss]

Hi 
i've got folowing problem:
working on SunBlade150 with Solaris 8 and sunFire v240 with solaris 9
when i try to input some latin2 characters for example ecaron to
NSTextView or NSTextField nothing happend, but latin2 characters from
source code such as messages works fine.

i've got gui 0.9.0 back 1.0.0 base 1.8.0

I've tracked this events:
for US: keymap:
 NSEvent: eventType = keyDown, point = { 80.000000, 269.000000 },
modifiers = 0, time = 3506431773.000000, window = 4, dpsContext =
0x12daa0,  repeat = NO, keys = 2, ukeys = 2, keyCode = 0x26

and for CS: keymap (czech)
NSEvent: eventType = keyDown, point = { 73.000000, 269.000000 },
modifiers = 0, time = 3505508662.000000, window = 4, dpsContext =
0x12daa0,  repeat = NO, keys = (nil), ukeys = (nil), keyCode = 0x26

i can see that keys and ukeys is nil for CS mapping so there be a
problem, but in other applications such as xterm, mozilla openOffice
everything works ok.

here is piece of CS: keymap

keycode  37 = plus 1 exclam
keycode  38 = ecaron 2 at
keycode  39 = scaron 3 numbersign currency
keycode  40 = ccaron 4 dollar currency
keycode  41 = rcaron 5 percent
keycode  42 = zcaron 6 asciicircum
keycode  43 = yacute 7 ampersand
keycode  44 = aacute 8 asterisk
keycode  45 = iacute 9 braceleft
keycode  46 = eacute 0 braceright
keycode  47 = Return
keycode  48 = Escape
keycode  49 = BackSpace
keycode  50 = Tab
keycode  51 = space
keycode  52 = equal plus percent
keycode  53 = SunFA_Acute dead_caron
keycode  54 = uacute slash bracketleft
keycode  55 = parenright parenleft bracketright
keycode  56 = SunFA_Diaeresis grave bar
keycode  57 =
keycode  58 = uring quotedbl Uring

Now i can't figure out why GNUstep doesn't get the ecaron or scaron
character from keyboard  even though other apps does.

thanks for help.
