* This program reads the Franctional UCA table and generates
* internal format for UCA table as well as inverse UCA table.
* It then writes binary files containing the data: ucadata.dat
* & invuca.dat
* Change history:
* 02/23/2001 grhoten Made it into a tool
* 02/23/2001 weiv Moved element & table handling code to i18n
* 05/09/2001 weiv Case bits are now in the CEs, not in front
