OK, I think I've worked out what's going on. The iso-8859-1 setting was probably left over from my previous Breezy Badger installation (I kept my home drive for the "fresh" install), so that's a red herring.
I created a new account for testing, and Konsole works fine. LANG is en_GB.UTF-8, Settings/Encoding is Default, and all punctuation marks that I can see in man pages display fine.
There is a problem with the console display, though, because LANG is also en_GB.UTF-8 here. The display does the "right" thing in rendering undisplayable characters as rectangles, but apart from that there are no "wrong" characters. If I unset LANG, all is well. Clearly LANG should not be set for consoles.
I also found another problem with my original Konsole settings, though. The default font in a new account is DejaVu Sans Mono, but I was using Bitstream Vera Sans Mono. In this font, word breaks are displayed as boxes, such as in gcc(1), where "remain-der" is split across two lines. If I change my font to DejaVu (actually I can't see any difference between the two fonts), the problem is resolved.
