Looks like another side effect of the quick & dirty fix for bug 280896.

As a workaround for now, enable Bi-Di text rendering in your konsole profile.

Any progress? Enabling Bi-Di text rendering made no difference FWIW, although I observe an improvement by *disabling* it...

Are you able to adjust Profile Settings->Advanced->Line Spacing such that it is usable for you?

I can confirm this on the newest konsole (2.13.2, KDE 4.13.2). Some lines are positioned incorrectly, and in effect cut off half way vertically. It's always the same lines for example in man pages. Reproducible always with all bitmap fonts I tested with. Enabling Bi-Di text changes the position from too low to too high, which is just as bad. Sufficiently high Line Spacing makes the whole line visible but still not correct. Curiously when moving the text cursor on a bad line, letters left of the cursor position correctly.

I'm sorry, please ignore the previous comment. My issue has nothing to do with unicode (though that I can also confirm and disabling Bi-Di text helps as mentioned earlier) but with seemingly random lines. It seems last comment in bug 280896 describes it too. Should I open a new bug for it?

With the Consolas font I'm seeing this issue, where a non-ascii character on a line will shift nearby text on the same line down and to the right. Disabling bi-di text rendering makes the text shift to the right but not down.

Still happens with KDE 15.12.3, KDE Framework 5.18.0, Qt 5.5.1. Disabling bi-di text fixes it completely for me - text is not even moving to the right.

Hallo guys,

it seems to me that it could be fixed here:
https://bugs.kde.org/show_bug.cgi?id=371687

Unicode printing is totally fine on my system, at least with all I could think to test.

Does the problem you reported still occur for you?
Can you post an example I can try on my system?
