slovenian keyboard support

[Rok]

I'm using slackware 10, KDE and Wine 20040914 (binary) and have problems using
specific letters:

---cut-here---
err:keyboard:X11DRV_ToUniCodeEx Please report: no char for keysym 01E8 (ccaron)
:
err:keyboard:X11DRV_ToUniCodeEx (virtKey=E2,scanCode=62,keycode=2F,state=10)
err:keyboard:X11DRV_ToUniCodeEx Please report: no char for keysym 01C8 (Ccaron)
:
err:keyboard:X11DRV_ToUniCodeEx (virtKey=E2,scanCode=62,keycode=2F,state=11)
err:keyboard:X11DRV_ToUniCodeEx Please report: no char for keysym 01B9 (scaron)
:
err:keyboard:X11DRV_ToUniCodeEx (virtKey=E0,scanCode=60,keycode=22,state=10)
...
---cut-here---

I'd need letters [cCsSzZ]caron [cC]acute [dD]stroke. Is there any this can be
resolved?
Thanks!

LP,Rok.
