Well, there are several reasons why a browser might fail to render a
character. The most common reason is lack of a glyph in the font(s) that the
browser uses.

In this case, however, the character reference does not denote any defined
character, since in Unicode, position 61510 decimal, F046 hexadecimal, is
unassigned. Or, more exactly, it is in the Private Use Area.
"Private-use characters are assigned Unicode code points whose
interpretation is not specified by this standard and whose use may be
determined by private agreement among cooperating users. These characters
are designated for private use and do not have defined, interpretable
semantics except by private agreement."

http://www.unicode.org/versions/Unicode4.0.0/ch15.pdf#page=17

So they aren't really useable in WWW authoring.

decimal 61510 is in the private use area, isn't it?

http://www.unicode.org/faq/casemap_charprop.html#8

the same codepoints in the PUA may be given different meanings in
different contexts, since they are, after all, defined by users and
are not standardized. If text comes, for example, from a legacy NEC
encoding in Japan, the same codepoint in the PUA may mean something
entirely different if interpreted on a legacy Fujitsu machine, even
though both systems would share the same standard codepoints

What are you trying to achieve? In a WWW context, you can't expect
WWW readers in general to see PUA characters the same as you do (as I
quoted from the Unicode FAQ), though there might be some ranges (e.g
Adobe) that would work quite widely, as long as users had the fonts
for them.

There's nothing wrong in principle with your HTML; you need to be
looking for a browser/OS/font issue, preferably on a group where your
browser and OS are on-topic. You don't seem to have mentioned any of
those yet, so I take it they'll be Windows and IE (just as in the old
days when people didn't mention OS and browser it always turned out to
be Mac and Mosaic, ho hum.) I have to tell you that IE, although it
makes quite a reasonable job of i18n in general, isn't very good at
handling oddball characters.

Well, Mozilla seems to think it knows what to display when I try it.
I'm not sure which font it's using to do it, though. It looks like
this (not including the boxing chars):

Is that what you expected?
