Tomasz-
- broken browsers - they should be upgraded, if someone has browser so old that it doesn't grok UTF-8, it's not going to grok CSS, PNGs, and other things we're using either. Unless we want to remove all CSS and PNGs, there's no point in not using UTF-8.
Is this true? All I know is that we had a *lot* of problems with broken special chars on the Meta-Wiki during the logo contest. I have no idea which browser broke them, but it seems to be a not totally uncommon one, perhaps in the 5% range. Given that a single edit by such a person will break an entire page, it might not be so wise to switch (but perhaps I'm missing something -- is Meta running UTF-8?).
