Support Unicode full case mapping and conversion.

Browse Source

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"
