foldfunction

What two ways of typing a name have in common: width (full-width letters to ASCII, half-width katakana to full), case, accents (except the two marks that make が and ぱ), katakana to hiragana, apostrophes dropped, and every other run of punctuation or space to one space. The lookups compare names folded, and so can a page.
