I use several types of terminals in my Slackware 13 distribution: xterm, rxvt, Konsole, and xfce's terminal emulator (Terminal 0.4.6). All of them read my .dir_colors file and, for the most part assign colors to file-types as I wish. The exception is html files and css files, (e.g. blah.html and blee.css).
The rxvt terminal has no problems, but none of the other terminals will colorize these files properly. The terminal emulator displays: [00:33mblee.css, (the first character looks like a small 2x2 array of 1's and 0's in a box. The above is cut-and-paste from the terminal.). Konsole displays: 33mblah.html. xterm doesn't even try to colorize html and css files, but leaves them white (default text color).
I would like to understand what is going on. Any ideas? TIA.
