Depending on some variables, that may not be hard to fix. What is hard to fix is creating easy ways to input the chars. On my keyboard, even something as simple as << and >> requires three keys for the unicode version, but only two for the ascii version. (Compose + < + < = «). Not only that, but I have to explicitly enable my compose key.

Almost paradoxically, it is much harder to enable unicode in something like PM, as the orignal poster discovered, and as I discovered when I hit preview on this node.

This is very true. I was actually thinking about the << problem the other day. I'm almost positive I can set up vi to automatically replace << with «, and I would bet that other major editors would be able to do the same. But yes, the problem comes when you add unicode characters, and suddenly I would have to add more substitutions to my vim files.

With vi, you can press C-k key key to do a compose action -- C-k < < is «. However, this is still a lot more keys then <<, which works just as well.
