Description:
It would be desirable for Search and especially for the "Go" functionality
(resolving a page title to an actual page without an intermediate search) to use
all sensible Unicode Foldings on the searched titles.

Unicode Character Foldings define[1] string transformations for making two
strings search-equivalent (different from Unicode normalizations, which make
strings content-equivalent). The folded title should not be stored instead of
the original title but in addition to it, and when searching, the comparisons
should be made between a folded search string and the folded title.

We already do certain forms of folding, such as case insensitivity, but we could
benefit from the full set of foldings, such as eliminating the difference
between minus and dashes and more.
