First, I'd suggest checking to see if you system agrees with you about that.
ben at Fenrir:~$ xlsfonts -fn "-*-helvetica-bold-r-*-*-16-*-*-*-*-*-*-*" -adobe-helvetica-bold-r-normal--16-116-100-100-p-0-iso10646-1 -adobe-helvetica-bold-r-normal--16-116-100-100-p-0-iso10646-1 -adobe-helvetica-bold-r-normal--16-116-100-100-p-0-iso10646-1 -adobe-helvetica-bold-r-normal--16-116-100-100-p-0-iso10646-1 -adobe-helvetica-bold-r-normal--16-116-100-100-p-0-iso8859-1 -adobe-helvetica-bold-r-normal--16-116-100-100-p-0-iso8859-1 -adobe-helvetica-bold-r-normal--16-116-100-100-p-0-iso8859-1 -adobe-helvetica-bold-r-normal--16-116-100-100-p-0-iso8859-1 -cronyx-helvetica-bold-r-normal--16-116-100-100-p-0-koi8-r ben at Fenrir:~$ xlsfonts -fn '-*-helvetica-medium-r-normal--12-*-*-*-*-*-iso8859-1' -adobe-helvetica-medium-r-normal--12-120-75-75-p-67-iso8859-1 -adobe-helvetica-medium-r-normal--12-120-75-75-p-67-iso8859-1 -adobe-helvetica-medium-r-normal--12-87-100-100-p-0-iso8859-1 -adobe-helvetica-medium-r-normal--12-87-100-100-p-0-iso8859-1 -adobe-helvetica-medium-r-normal--12-87-100-100-p-0-iso8859-1 -adobe-helvetica-medium-r-normal--12-87-100-100-p-0-iso8859-1Mine certainly recognizes those patterns, and can match them from the installed fonts (which is why, I suppose, I don't have that problem.
If yours can't - and I suspect that this is what you'll find - then you need to do a little investigative work to find out what's happening. First, you'll need to find out what X considers your font directories:
ben at Fenrir:~$ xset q|grep -i font Font Path: /usr/share/fonts/X11/misc/,/usr/share/fonts/X11/100dpi/,/usr/share/fonts/X11/75dpi/,/usr/share/fonts/X11/cyrillic/,/usr/share/fonts/X11/TTF/epson/,/usr/share/fonts/X11/TTF/extra/,/usr/share/fonts/X11/TTF/freefont/,/usr/share/fonts/X11/TTF/openoffice/,/usr/share/fonts/X11/TTF/thryomanes/Lots of goodies, but those first three are the ones we really care about - we can live without the others, but these are the base fonts for X. They may be in a different place in your list; the important bits that we're looking for are the 75dpi/100dpi/misc directories.
(If you don't get some similar output, you'll need to verify that your '/etc/X11/xorg.conf' or '/etc/X11/XF86Config-4', whichever one you use, contains at least those critical directories in the "Files" section, as 'FontPath "/usr/share/fonts/X11/misc/"', etc.)
Now that you know where your fonts live, you need to check your font listings in those directories. These are contained in per-directory files called 'fonts.dir'. Here we go (note that you'll need to use whatever your font directories were, since there are at least two possible options):
ben at Fenrir:~$ grep -h -- -helvetica /usr/share/fonts/X11/100dpi/fonts.dir|head -5 helvB08-ISO8859-1.pcf.gz -adobe-helvetica-bold-r-normal--11-80-100-100-p-60-iso8859-1 helvB08.pcf.gz -adobe-helvetica-bold-r-normal--11-80-100-100-p-60-iso10646-1 helvB10-ISO8859-1.pcf.gz -adobe-helvetica-bold-r-normal--14-100-100-100-p-82-iso8859-1 helvB10.pcf.gz -adobe-helvetica-bold-r-normal--14-100-100-100-p-82-iso10646-1 helvB12-ISO8859-1.pcf.gz -adobe-helvetica-bold-r-normal--17-120-100-100-p-92-iso8859-1If you don't get something similar to the above results, 'cd' into each of those font directories in turn and verify that you have the appropriate font files there (you can do a quick check against 'dlocate xfonts-{75,100}dpi'). If you do, then run, as root, the 'mkfontdir' command which will rebuild your 'fonts.dir' (it never hurts to do this in case of doubt) and follow it up with 'xset fp rehash', which will reread the font databases in the path.
That pretty much covers troubleshooting X fonts from one end to the
other. If this doesn't fix it, shoot your computer and bury it with a
stake through its CPU.

Thanks, I really appreciate your taking the time to put together this guide to the mysteries of X fonts. It helped a lot to reassure me that my eyes weren't deceiving me over the last few days.
It seems Debian testing was just going through some font troubles, and right enough, today everything is back to normal again after another dist-upgrade and restarting X a second time. So I guess it was a bit like a spot of bad font-weather.
Hope things went well with the hurricane and you managed to find shelter for your boat.
Peter.

Slightly amused that you weren't relocated here, so here it is:

That's because I'd mentioned it explicitly in a couple of my recent
articles, Thomas. Your fame is assured.

Oh, that one petered out - when it went over us, we didn't even get any wind. We did, however, put out a large new anchor and chain just in case. There's another storm, Florence, in the offing -

- but for the moment, the projected track is fairly innocuous.

Heh -- you think I actually read Linux Gazette?

What's important is that your adoring fans do.
Really, there's no point in reading any of it. Did you actually think
that it's possible to understand all this Linux stuff? According to a
Large Unnamed Company based in Redmond WA, it's just way too complex for
the human mind, and only weird techno-freaks could ever get it. Who are
you going to believe, some wild-eyed fringe radicals or a reputable
company with billions of dollars? The choice is obvious.
