Hi, I would like to know how the derived files that one can find in the UNIDATA folder are generated? I am trying to have IBM's ICU library support older versions of Unicode than the one it currently supports (3.0.something), specifically Unicode 2.1.x. ICU needs the following files: UnicodeData.txt SpecialCasing.txt DerivedNormalizationProperties.txt NormalizationTest.txt UCARules.txt FractionalUCA.txt CaseFolding.txt Mirror.txt If I look in Public/2.1-Update4 I can find the first two files for Unicode 2.1.9. A number of the other files either say they have been algorithmically generated (e.g. DerivedNormalizationProperties.txt) or look like they have. I am interested in knowing what tools have been used to generated these and if I could get these tools and use them to generated the same files for another version of Unicode. I am sure I could write some tools myself (following the instructions in DerivedProperties.html for DerivedNormalizationProperties.txt for example) but I am looking for a quicker way to generate these. Thanks for any help on this, YA PS: Also I hope that all the derived files will be stored in the non-UNIDATA folders as Unicode is revised. They'll be helpful for people that need to build a Unicode library for a very specific version of Unicode. -- My opinions do not necessarily reflect my company's. The opposite is also true..
