line-height problem when using ž character

[Puggan]

If I write a line containgin ž in konsole or kwrite, the line height gets messed up. Is the default font broken, or is it the apps? Didn't know where to report the bug, so "ask ubuntu" sounded as a good start.

How to reproduce:

    Open kwrite, kate or console
    Write __
    Then add a ž on the same line so you now have __ž

Expected behavior:

    The other chars should stay the same when I add a ž

Current behavior:

    The __ is no longer visible, guess all text get their lowest pixels removed, the _ char only have lower pixels, so easier to spot there.

In konsole, the cursor position make some differences, think it draws the text in 3 parts: before, on, and after cursor, so only the parts that include the ž char gets the error, if you wirte __ž__ and put the cursor on the ž char, you can see the __, but if you write __ž__ž__ you can see the 3 different parts acting.
