           Summary: konsole (as opposed to gvim) doesn't suppress
                    ligatures on fixed fonts, breaking things like

           Product: konsole
           Version: 2.4.5
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: konsole-devel at kde.org
        ReportedBy: vassilii at tarunz.org

difference in ligature handling of konsole (broken) and gvim (ok) using the
same fixed font

Version:           2.4.5 (using KDE 4.4.5) 
OS:                Linux

please see the attached screenshot - konsole and gvim are set to use the same
font there, and both display the result of "ls -C" in the same directory.
GVIM's behaviour is expected, konsole's is not. The font used is cm-unicode
"CMU Typewriter Text", size 18.

Reproducible: Always

Steps to Reproduce:
install cm-unicode (see screenshot for distribution URL)
set konsole and gvim to use the font CMU Typewriter Text, size 18 (or any other
fixed font with ligature markup inside)
do ":r!ls -C" in a directory that has filenames that match the ligatures inside
gvim and "ls -C" at the command prompt in konsole

Actual Results:  
see konsole's window in screenshot

Expected Results:  
see gvim's window in screenshot
