Most of the equivalent sequences in character_fallback_substitutions.html
are NFC and NFKC that means normalization using the decomposition property
whose equivalence we already argeed to implement in the search.

A few of the equivalent sequences are marked "Explicit" and
all of them are defined in a separate very small file

http://unicode.org/repos/cldr/trunk/common/supplemental/characters.xml

whose mappings we could also add to our equivalence tables explicitly.
