Thank you both for your tips on gperf, Vasilis and ha shao.
I tried it a few days ago on Debian (apt-get install gperf does it)
and I was really amazed by it.  :-)

As for BIG5-HKSCS table for glibc, James has come up with an excellent
solution in keeping the size down.  A very neat summary index table. 
:-)  More work (esp. the charmap file) is needed before submitting to
glibc, but yes, I am really impressed by his work.  :-)

I'll play with gperf and hashing after some deadlines at work.  Very
helpful tools indeed.  :-)

Cheers,

Anthony
