When a character wider than the monospace font is used in Konsole, the cursor appears to cover half of the last letter of the line. See attached screenshot. The top line of the screenshot is from root, which has the stock Bash prompt. The lower line is from my user, which has a wide non-ASCII character leading the prompt. Note that this issue is not limited to only non-ASCII dingbats like that used in the screenshot. My own native language is not represented in ASCII either, and may be displayed using a font that is wider than the ASCII font used for ASCII.

However, certainly some of the last comments on that bug are conflated with this issue.

It truns out my previous guessing may be wrong. That symbol is defined as narrow(actually neutral)according to Unicode data[1][2]. However the screenshot shows that it is displayed as Wide, taking the width of two cells. I can reproduce the problem when using some fonts, while not when using other fonts. At the moment I'm not sure whether this is a problem of fonts or a problem of Konsole. which font is used in your screenshot?

I won't be at my computer for a few weeks to check, but I can confirm that the phenomenon is in fact font-dependant. All the fonts that I like suffer this problem, but some very ugly fonts do not.

However I'd like to add that just like Cohen said, it's dependent on the font that's used. I've recently tried to set Monaco (which is wider than the standard font used) as my Konsole font, but found that konsole eats up a little of the prompt when I set the font to that. I'm thinking it's got something to do with the character width.

Sorry, I did'nt get that the comment box in the web interface would be the message with my attachements. Anyway, I found that bug too, using monofur font. I also confirm it's font dependant, I have no problem with any other font like Deja Vu or Monospace. Although I patched it with powerline () witch gives the arrow-like character in prompt, the problem actually come from the 'inverted A' and 'weird E'. As you can see, the bug doesn't occur when the problematic glyph is the first character after prompt (the inverted A), which is just cropped to a normal width wharacter.

In my experience, this occurs with all fonts. Changing the font (either face or size) will solve the problem temporarily; after exiting and restarting Konsole, the problem appears again regardless of the current font.

(Note that the character in the original screenshot doesn't take up two cells; it takes about one and a half.) I think the problem is that Konsole is rendering each row as a regular line of text. The original reporter's terminal font apparently doesn't have an airplane glyph. So the font engine searches for a font that does, and finds one, whatever it may be. But this new font probably isn't monospace, so the glyph isn't the same width as the rest of the characters in the terminal. Konsole blindly prints it anyway and places the next character immediately following it, even though this is now completely misaligned from the grid. The cursor is apparently rendered separately (makes sense, since it's not a character), so it gets drawn in the appropriate grid cell. What Konsole /should/ be doing is either shrinking the substituted character to fit in a cell, or forcibly rendering every single character at its correct position (even if this makes some overlap). This has been a bug for as long as I've used KDE. It makes using non- ASCII characters for any reason basically impossible — my prompt, irssi, vim, roguelikes, anything that uses interesting characters causes the cursor and columns to become misaligned. I've had to switch to a libvte-based terminal, which correctly handles this by overlapping characters when necessary.

I think Konsole should warn user about non-monospace characters in selected font or try to calculate right cursor position. Something should be done to eliminate users confusion.

It wouldn't even occur to most of them that it was something they needed to do! So in <http://launchpad.net/bugs/932958> I suggested that this be done lower down in the stack -- perhaps in fontconfig, perhaps in Pango (or whatever KDE's equivalent of Pango is). > or forcibly rendering every single character at its correct position (even if this makes some overlap). This is what Gnome Terminal does right now, and people really don't like the overlap.
