Sorry, I disagree. First, collation data is overkill for search,
since the order information is not required, so the weights are simply
wasting storage. Second, people do want to find, e.g., "²" when they
search for "2" etc. I'm not saying that they _always_ want that, but
sometimes they do. There's no reason a sophisticated text editor
shouldn't support such a feature, under user control.
