Dear Maintainer,

I am using urxvt with the following configuration:

urxvt*background : black
urxvt*foreground : white
URxvt*font: xft:DejaVu Sans Mono:pixelsize=14:antialias=true:hinting=true
URxvt*boldFont: xft:DejaVu Sans Mono:bold:pixelsize=14:antialias=true:hinting=true
urxvt*scrollBar : false
urxvt.perl-ext-common: default,tabbed

Underscores do not appear on the terminal. If I switch pixelsize to 13 or 15, underscores do appear.

Thanks.

I recently reinstalled my Debian system, and while I was at it, I
deleted my old ~/.fonts.conf because it was throwing warnings with
applications; shortly thereafter, I realized that I was no longer
seeing any underscores in my terminal output, nor were the underscores
being fancily used for italics or something.

Googling, I realized it was not a Bash problem but a Urxvt problem,
and found a long Arch Linux thread complaining about exactly this
problem: https://bbs.archlinux.org/viewtopic.php?id=125749

They noted that simply avoiding 14-point font made the problem go
away, and as it happened I had a key shortcut to increase the font in
Urxvt. Here is the original broken appearance using a 14-point font
(note that in the second-to-last line, there are no underscores even
though there are two):

Here is the same terminal, but having increased to 18-point font:

Now the underscores are clearly visible.

As a workaround, I'm going to try editing my .Xresources to read
15-point rather than 14-point.

My ~/.Xresources reads:

Dear all,

I also have this problem with Jessie.

URxvt.font: xft:bitstream vera sans mono:size=8

URxvt.scrollBar: false
URxvt*depth: 32
URxvt.modifier: alt
URxvt.MetaSendsEscape:          true
URxvt.eightBitInput:            false
URxvt.termName:xterm-256color

Best regards,
Dr. Carsten Otto
