I infrequently find myself on Joel Spolsky's site as the result of a search for something or other. It's not really a blog but a collection of articles on many different (it/web/developer) topics. The stuff he writes is ALWAYS interesting.
With that in mind, I finally added his Article Archive to the list of sites I visit regularly, just to see what's there.
I don't know how I missed this article previously, given it's relevance to me and my work, but The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!) is my 'read of the week'.
