The syntax .UR http://example.com paired with .UE will create
links which one can interact, if the pager allows that. One
way to see the effect is ask the man(1) command to use browser
display, e.g.:
man -H man7/uri.7
("\:" is optional groff syntax to permit hyphenless line breaks.)

Nowadays mandb has provision to understand a character set
encoding that is explicitly indicated in the first line
of the source. As pointed out by Colin Watson, including
such an explicit indication on pages encoded in anything
other than ISO 8859-1 or UTF-8 is useful for man-pages
that aren't shipped in UTF-8.
