Prior to my migrating from RHEL 5.5 to 6.0, when I used characters
U+22b3, U+22b5, U+227b, U+227f, U+2280 in formulae coded within
OpenOffice Math (the formula editor) of OpenOffice 3.2.1, the
document displayed these when viewed in OpenOffice, and an
exported PDF displayed these when viewed with Acrobat readers.
Now, when the very same version of OpenOffice is used in RHEL 6.0,
these character becomes invisible both in .ODTs and in .PDFs.
This problem obtains, in fact, whether I use the distribution of
OpenOffice supplied by OpenOffice.org or that provided by Red Hat.
I don't know whether this problem obtains from changes in
fontconfig, from a change in the installed set of fonts, or from
some other source.
I think it's a straightforward bug in OOo: those characters are
perfectly OK outside a formula, and they're visible when you're
editing the formula, they're just not visible when it's rendered on
the page.
I have file an issue report (116132) with OpenOffice:
<URL:http://www.openoffice.org/issues/show_bug.cgi?id=116132>
The developer looking at he issue reports that it is not reproduced on
Solaris or on Suse 11.
I ask others on this list to see if the problem is reproducable on
their systems (try rendering
a`≻`b
in an OpenOffice document), and if so then to chime-in at the report,
in order to move the status from "unconfirmed".
My thanks to those of you who do.
