In your arc article: http://www.paulgraham.com/arc0.html
you have the following few sentences: I realize that supporting only Ascii is uninternational to a point that's almost offensive, like calling Beijing Peking, or Roma Rome (hmm, wait a minute). But the kind of people who would be offended by that wouldn't like Arc anyway.
Here's the issue: "the kind of people who would be offended by that" - I realize that "that" refers to ASCII only support, and I agree with your statement. But it took me two minutes to figure that out. Indeed "that" might as well refer to Chinese people being offended by the colonial label of Peking instead of using Beijing. I thought you might want to fix this infelicity of expression.
