Right, if you look at the output from man(1) you will see that this
text appears as
c^Hcm^Hmd^Hd
etc. It's backspacing and repeating the chars which would give bold on
a printer (one that could backspace). The interpretation of this is
controlled jointly by more(1) and the termcap entry for cons25. In an
xterm it appears as bold text.
Here is a reply I made to almost the same question ~6 months ago,
hopefully it will help you. Note that termcap is traditionally in /etc
but in FreeBSD /etc/termcap is a symlink to /usr/share/misc/termcap.
You *must* run cap_mkdb in /usr/share/misc/, not /etc.

Actually, it's a combination of the function of the pager *and* the
termcap entry for that terminal. The text that appears in inverse
video on the console is underlined (f^H_o^H_o^H_ in the output from
man(1)) and appears as such in an xterm. The termcap(5) entry for the
console (cons25) has no underline attributes defined and in
/usr/src/usr.bin/more/screen.c if there is no underline attribute
defined for the terminal it uses "standout mode", i.e. inverse video.
If Alexey wants underlining to appear as yellow on black as he says
then in /usr/share/misc/termcap change the line
:tc=cons25w:
in the definition of
cons25|ansis|ansi80x25:\
to
:us=\E[40;34;1m:ue=\E[m:tc=cons25w:
^^ ^^
|| fg colour
||
bg colour
then, as root, run ``cd /usr/share/misc ; cap_mkdb termcap'' and then
try ``man chmod'' on the console.
For a visual "list" of colour combinations, run this script (the
numbers along the top of the display are the bg colours and the ones
at the left are the fg colours):
#!/bin/sh
# Display ANSI colours.

If I buy a copy of WinDelete, and it doesn't delete Windows,
am I entitled to my money back?
