My version of Cyberbit doesn't display the cyrillic characters as well.
All of the unicode fonts that I use are converted with John-Mark Bell's
!TTF2f and their cyrillic characters seem to work fine, at least in
!NetSurf as well as in !Dict. As said before, all other encodings that are
supported by !XChars display their characters properly.

I'm afraid that I don't understand a bit of what you explain about
artificial number-based glyphs and all that, but I can assure that none of
the unicode fonts here have an IntMetrics<n> file. Actually, I don't think
that I've ever seen such file.

That more or less describes the dead end in which RISC OS currently is
trapped, at least when it comes to unicode. I really would like to be able
to use unicode fonts in, say, OvationPro, and to send e-mails is different
encodings, for which I have to switch to our Windows laptop now.

At the moment, I can at least read cyrillic e-mails on my loyal Iyonix, by
dumping their contents into !Edit, that I pushed to use the ArialUni\EUTF8
font. One of the very first steps towards a more convenient unicode aware
system would be the ability to choose fonts with this \EUTF8 extension
directly from the appropriate menus rather than configuring them in text
based boot files or worse. And while !Edit is able to display unicode
indeed, editing is a real nightmare and printing is completely out of the
question. But probably you're right: it's merely a matter of updating the
applications rather than rewriting the OS. Will it ever happen?

Kind regards,
