This document describes the process of updating the files in the Mozilla codebase that are generated from Unicode data files.
Case conversion
- Download the latest version of UnicodeData.txt from the Unicode website. The current version can be found at http://www.unicode.org/Public/UNIDATA/UnicodeData.txt.
- Copy this file to intl/unicharutil/tools/UnicodeData-Latest.txt in the mozilla source tree
- Until bug 210501 is fixed you will have to edit UnicodeData-Latest.txt by hand and delete all the lines for codepoints above FFFF
- Run perl gencasetable.pl This creates a new version of intl/unicharutil/src/casetable.h
Character properties
- Download the latest version of UnicodeData.txt from the Unicode website. The current version can be found at http://www.unicode.org/Public/UNIDATA/UnicodeData.txt.
- Copy this file to intl/unicharutil/tools/UnicodeData-Latest.txt in the mozilla source tree
- Run perl gencattable.pl This creates a new version of intl/unicharutil/src/cattable.h
- The previous step will probably issue warnings like the following:
WARNING, Unicode Database now contain characters which we have not considered. change this program !!! Problem- U+010900 - U+010907 range
In this case, you will need to edit @range in gencattable.pl to include the new ranges
