They use left and right angle bracket special character escapes

I think that's a bug in groff. It should use plain <> for URLs, at least
for tty output devices.

I checked, and yes, it renders some character (the character depends
on the terminal: on tty I've seen a diamond, and on the xfce terminal
something similar (but slightly different) to a parenthesis).

Your console font doesn't support U+2039/U+203A and uses diamond as a
replacement character.

I have this in /etc/groff/mdoc.local and /etc/groff/mdoc.local as a
work-around:

.  if '\V[TERM]'linux' \
.    tr \[la]<
.  if '\V[TERM]'linux' \
.    tr \[ra]>

(In the long run, I should probably fix the font instead.)

After seeing Branden's answer to Michael (Escaping hyphens),
I've seen groff_char(7), and I found that my tty correctly supports
U+2039 and U+203A.  I clearly see the symbols I would expect: something
quite similar to plain <>, but a bit more obtuse.

In the XFCE terminal, I also see something quite expected: a slightly
smaller version of <>.

But both show me very different characters for .UR/.UE.
tty displays a diamond, and XFCE term displays (a weird version of)
round parentheses.

So... does it mean there's a bug in .UR/.UE?

Thanks,

Alex
