Yes. Pressing Ctrl+Plus/Minus changes them. Without Xft, it chooses from
a list of 6 predefined fonts. With Xft it adjusts the size by some
specified increment.

BOLDFONT enables drawing bold characters using a different (presumably
bold) font. Without Xft this font can be specified using -fb. With xft
the font used is the same as the current font. The weight of the bold
font can be specified using -xftbwt.

They are to draw tab titles. IIRC xftpfont is a (presumably)
proportionally spaced font to draw inactive tab titles. xftPfont is a
(presumably) bold one for the active tab title.

I don't know squat about multichar stuff. Good luck.

Here's the font options from my ~/.mrxvtrc
#
# Ugly X11 fonts

# Xft settings. As of mrxvt-0.5.0, Xft support is quite good, so use Xft by
