* How to generate various properties files in intl/unicharutils/tables and
header files in intl/unicharutils/src
( written by Jungshik Shin for bug 210502

1. Grab the latest version of idnkit at http://www.nic.ad.jp/en/idn/index.html
(http://www.nic.ad.jp/ja/idn/idnkit/download/index.html )
2. There are three files we need in the kit:
generate_normalize_data.pl, UCD.pm and SparseMap.pm
3. a. Download the following Unicode data files :
CaseFolding.txt,CompositionExclusions.txt,
SpecialCasing.txt, UnicodeData.txt
b. Rename UnicodeData.txt to UnicodeData-Latest.txt
The latest version is, as of this writing, in
ftp://ftp.unicode.org/Public/4.1.0/ucd
4. a. Run generate_normalize_data.pl and save the output to a temporary file
b. Edit the file
- remove the case folding part (search for 'Lowercase' and delete
all the lines following it) because we have separate scripts for that,
- replace 'unsigned short' and 'unsigned long' with 'PRUnichar' and
'PRUint32'
c. Replace the actual source part (after the license) of
intl/unicharutil/src/normalization_data.h with the file you edited.
5. Generate casetable.h and cattable.h with gencasetable.pl and gencattable.pl
Just running them will put casetable.h and cattable.h in the right place.
