Craig Andera's blog.
Joel posts another great one, this time on the basics of Unicode. He rightly points out that every developer should know this stuff.
But you all know this already, because you all read Joel, right? Right!?!?
Almost no use, quoting something from Joel's site. Allmost everyone with a blog reads his site... Just do some Feedster searches on unicode in a few days and you'll see :-)
What can I say - guilty as charged. ;)
