What exactly isn't? Other than the below problem, it looks fine on
cursory glance in firefox and ie.

Not in my mail client here. I can't find this string on your page,
but I see a lot of "∧" there in firefox and ie.

There are two confliting definitions for CHARSET at the header:

First, you have, at line 5:
<META HTTP-EQUIV="CONTENT-TYPE" CONTENT="text/html; charset=utf-8">

But, at line 17, you have:
<META HTTP-EQUIV="Content-Type" CONTENT="text/html;CHARSET=iso-8859-1">

Here on my computer,
a ⋀ b
looks like an error... I got:
'a', then a symbol for unknown char, then 'b'.

If you want a glyph similar to a '^', replace the "&and;" ocurrences for "∧". It seems that the "&" strings were generated in a bad conversion from ASCII (or other charset) to HTML.

You mean, in the sense that everything isn't Unicode already? Editing in UTF-8 and setting the character set is a good way.

I get a timeout.

Yes. I added it to my featureful local homepage:

<html><head><title>Home Page</title></head><body>
Unicode test: ⋀</body></html>

Then again, ^ also looks like a wedge product to me.

Yeah, that's definitely a problem. HTTP-EQUIVs are sort of evil
anyway. If you're running your own server you should just configure it
to send the right Content-Type: HTTP header.

Looks fine from here in Mozilla Firefox 1.5.0.3 (Windows XP). You may need a font that contains the ∧ character (Arial Unicode MS, Lucida Sans Unicode, Code2000, etc.)

If I paste it into a text file and view it in Firefox it does.

I found a page which helpfully explains "Although Microsoft's Internet
Explorer browser is widely used, it does not have as good Unicode
support as some of its competitors. For better Unicode support, you
may like to consider installing and using either Firefox or Opera,
both of which are available for Windows, Mac and other operating
systems." Does Bill Gates have his head up his ass, and if so, when
does he plan on pulling it out? Why in the world would IE not be
up-to-date with Unicode support?

Now I don't know whether to revert the page or not.

I will point out that Windows NT has been unicode down to
the kernel since it was first released -- way ahead of any
other OS (still ahead?).

As for Internet Explorer, you are aware it still contains
NCSA Mosaic code?

As far as heads up asses go, I note that Firefox with 7
tabs open is currently using 120MB of memory. IE with
about 30 tabs open is using 35MB and it's way faster.

You shouldn't need to reply on an operating system to get a browser to
work.

No, but it doesn't surprise me.

Agreed. I'm just saying, not everything they do is numskullish.

[...]

This is getting really off-topic, but my GNOME desktop fully supports
Unicode. The Linux kernel and filesystem know nothing about character
encodings, but they're 8-bit clean to allow the use of any encoding,
which seems like a good design to me.

Not a single filesystem, but several filesystems are supported, like:

ext2
ext3 (with journal)
xfs
reiserfs

Strange filesystems like vfat and ntfs are supported, and there are GNU/Linux distributions that can be installed on such filesystems.

This is a excerpt from manual page for "mount", the program responsible to mount/umount filesystems:

<<<
The argument following the -t is used to indicate the file system
type. The file system types which are currently supported include:
adfs, affs, autofs, coda, coherent, cramfs, devpts, efs, ext, ext2,
ext3, hfs, hpfs, iso9660, jfs, minix, msdos, ncpfs, nfs, ntfs, proc,
qnx4, ramfs, reiserfs, romfs, smbfs, sysv, tmpfs, udf, ufs, umsdos,
usbfs, vfat, xenix, xfs, xiafs. Note that coherent, sysv and xenix
are equivalent and that xenix and coherent will be removed at some
point in the future -- use sysv instead. Since kernel version 2.1.21
the types ext and xiafs do not exist anymore. Earlier, usbfs was known
as usbde- vfs.

Right, and what I meant was that the generic Linux filesystem code,
which handles all of these, is 8-bit clean, so as long as the
underlying filesystem has a way of storing arbitrary data (all of
these do), Linux will let you use unicode filenames or whatever.
