ISO-8859-8 font in gnome-terminal on RH8.0

[Uri Elias <elias techunix technion ac il>]

I would like to use in gnome-terminal an ISO-8859-8 (hebrew) font,
for example,  /usr/X11R6/lib/X11/fonts/misc/10x20-ISO8859-8.pcf.gz
In RH 7.2 such font automatically appeared in the font menu as
"fixed(heb)". In RH 8.0 no suitable font appears in profile -> fonts.
Is there a way to add a font?  Perhaps from command line?

A related question is about background colors.  I kept on the desktop
launcher icons for terminals on other computers, each with a different
color, to distinguish them easily.  On RH 7.2 it was done by
command line "gnome-terminal -bg yellow ...", etc.  How can I make on
RH 8.0  commands/launchers with different colors?
