To answer a question on HomoLudens, I’m not sure if Radio will handle Irish/Gaelic languages, let’s try
This line is Irish using 8 bit charaters:
Ní foclóir iomlán é seo, ach tá súil againn go mbeidh sé úsáideach d’oifigigh atá ag iarraidh teacht go tapaidh ar fhocail agus ar abairtí a úsáidtear go rialta ina réimsí féin.
This is the same line using (I think) Unicode. I’ll have to check out the source after this upstreams:

Here is Hawaiian as Unicode (I already know this works):
‘O Keola Donaghy ko?u inoa. He haum?na ??lelo Hawai?i au ma ka papahana laeo?o ma ka mo?okalaleo a me ka ??lelo Hawai?i ma ke kulanui o Hawai?i ma Hilo.
Doing the diacritics in both language in Unicode is dependant on your browser’s support for the Unicode. Radio is not Unicode compliant under OS X, so I can’t type or edit any of the diacriticts required for Irish or Hawaiian directly in Radio. Safari is Unicode compliant, and by what means I don’t know, but the rendering of said text to my website on http://radio.userland.com works fine for me. So far.
