Ah, right. I wondered if it was fairly straightforward because you
already render the blobs for lists, and lines for <HR> and table
borders and suchlike.

Rather than have another load of calls or a new API capable of
rendering specific codepages, would it be possible to add a single
function to the OS (or ttf.library maybe) which says "use this
codepage". You pass it a pointer to the conversion table and then all
rendering calls coming from that task will get that codepage. By
default, an old app which doesn't know about codepages will get the
Latin 1 page because it won't ask for another.
It would be fairly pointless embedding this into the existing OS
text() etc. calls since they mostly deal with 8-bit fixed bitmap fonts
anyway. Those things which can deal with it, like ttf.library, are the
things which would need changing. (Not that I have the faintest idea
of the ttf.lib API, or anything about codepages beyond what you've
written, so sorry if this is all rubbish).

It's good to have support for what you can reasonably do under the
current situation, at least. :)
Cheers,
