To cut a long story short, try using the "Linux" font (Settings->Font->Linux).

In general, any iso10646-1 (unicode) font should do. The usual "fixed" fonts 
are iso8859-1 and do not contain any greek letters (beside the pi, 
ironically, see below). Any iso8859-7 (latin/greek) font should suit also.

You should be aware what font you're using. QT/KDE does font selection the in 
an ms-windowish style, so it is not made explicit which X11 font is actually 
selected. Konsole's font selection is even worse in this respect. No wonder 
you are confused.

Konsole is accompanied by a README.font document containing related 
information.

A fixed pitch font should have all glyphs with same width but some could come 
up with a width of 0 for undefined characters. The reason is, that the font 
designer did not set a default character, e.g. a box. That means the font it 
is broken. konsole cannot help this.

see above. They have corrected the font, meanwhile.

Pi also appears as a graphical character in every well crafted fixed font, 
but that's a different story (see addch(3ncurses) ACS_PI), as i assume you 
simply want to type greek text in vi.

Konsole can only display those glyphs that are present in the font you 
select. Use the xmbdfed program (File->Import->Server Font) to inspect the 
fonts.

has caused the attached bug report to be marked as done.

This means that you claim that the problem has been dealt with.
If this is not the case it is now your responsibility to reopen the
bug report if necessary, and/or fix the problem forthwith.

(NB: If you are a system administrator and have no idea what I'm
talking about this indicates a serious mail system misconfiguration
somewhere.  Please contact me immediately.)

The greek letter "pi" does not appear at all in a konsole window.
Instead a box is displayed in it's place.
This error appears only in konsole, not in other KDE applications.

In the past, this problem was a little bit different. Instead of displaying this letter, nothing was displayed, making the positioning of characters *after* this letter almost impossible.

Now at least in the "pi" letter position, there is a box.

I have to say that this letter is more or less special. The position of this letter is double": one for the mathematical symbol "pi" and one for the greek alphabet letter "pi".
Of course in both cases, it *is* the same letter, so most fonts have this glyph only once (which is right).

So what I suspect is that konsole couldn't understand this situation.
