Support Unicode full case mapping and conversion.
Generate tables from Unicode SpecialCasing.txt to support more
sophisticated case mapping behavior:
* support case mappings to multiple codepoints, such as "ß"
uppercasing to "SS"
* support conditional case mappings, such as the "final sigma"
* support titlecase variants, such as "dž" uppercasing to "DŽ" but
titlecasing to "Dž"
