           Summary: konsole does not fully emulate xterm/VT102/VT220
                    compatibility
           Product: konsole
           Version: 2.0
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: konsole-devel kde org
        ReportedBy: hunteke earlham edu


Version:           2.0 (using KDE 4.0.5)
Installed from:    Ubuntu Packages
OS:                Linux

The problem is that konsole does not seem to completely emulate xterm compatibility.  It seems to emulate positioning and things, but that's about it.  For instance, this test function in bash will dynamically change the font size in xterm, but fails in konsole.  (It fails in gnome-terminal as well, FYI.)

function font() {
	font_size=11
	font_weight="medium"
	if [ "$1" == "big"    ] || [ "$2" == "big"    ]; then font_size=26; fi
	if [ "$1" == "bigbig" ] || [ "$2" == "bigbig" ]; then font_size=34; fi
	if [ "$1" == "bold"   ] || [ "$2" == "bold"   ]; then font_weight="bold"; fi
	_font="\e]50;-*-lucidatypewriter-$font_weight-r-*-*-$font_size-*-*-*-*-*-iso8859-*\007"
	echo -ne "$_font"
}

# execute with '$ font big'

I also have the ability to change my background color with escape sequences in xterm, but not so in konsole.  For instance, this bash code works in xterm:

w='rgb:ff/ff/ff'  # white
g='rgb:aa/aa/aa'  # light/linux gray
b='rgb:00/00/00'  # black

w_background="\e]10;$b;$w;$b;$b;$b;$b;$w;$w\007"
g_background="\e]10;$b;$g;$b;$b;$b;$b;$w;$w\007"
b_background="\e]10;$g;$b;$b;$b;$b;$b;$w;$w\007"

# execute with '$ echo -ne $w_background'
# execute with '$ echo -ne $g_background'
# execute with '$ echo -ne $b_background'

A reference for the different options and escape sequences: http://rtfm.etla.org/xterm/ctlseq.html

I think this bug is not the same, but is related to these bugs about TERM=xterm
