I thought Dan was talking about something equivalent to the m//i functionality.
Would it, or should it, be possible to tell m// to treat Katakana
characters as the same as hiragana characters, in much the same way as m//i
treats UPPERCASE the same as lowercase? Canonicalization won't get you that.
My feeling is that the hooks should be there, but the specific equivalence
mappings should be in the library, not the core.
