More on non-latinate languages and RSS

Andy Carvin has paid attention to some of the issues related to non-Latinate languages and creating RSS feeds and has some comments about how the UNICODE project has helped power non-Latinate sites (and therefore their RSS feeds).
He writes: “For languages with RSS support, knowledge gets produced and disseminated at a rapid pace, allowing more online knowledge to be produced, and an expanding community of people able to talk about this knowledge and contribute even further to it. But for languages that can’t be transmitted via RSS, they’ll be stuck sharing content at a much slower pace, to smaller, less-connected audience.”
So, what do readers know about producing RSS feeds in Chinese, Vietnamese and Cyrillic languages?
Any experts out there? Inquiring minds need to learn more.
