| |
| * update FractionalUCA.txt and UCARules.txt with new canonical closure |
| |
| * genpname |
| - run preparse.pl |
| + make sure that data.h is writable |
| + perl preparse.pl \cvs\oss\icu > out.txt |
| |
| * uchar.h & uscript.h & uprops.h & uprops.c & genprops |
| - new block & script values |
| + script values already added in ICU 3.6 because all of ISO 15924 is now covered |
| |
| * build Unicode data source code for hardcoding core data |
| C:\cvs\oss\icu\source\data>NMAKE /f makedata.mak ICUMAKE=\cvs\oss\icu\source\data\ CFG=debug uni-core-data |
| |
| ICU data make path is \cvs\oss\icu\source\data\ |
| ICU root path is \cvs\oss\icu |
| Information: cannot find "ucmlocal.mk". Not building user-additional converter files. |
| [etc.] |
| Creating data file for Unicode Character Properties |
| Creating data file for Unicode Case Mapping Properties |
| Creating data file for Unicode BiDi/Shaping Properties |
| Creating data file for Unicode Normalization |
| Unicode .icu files built to "\cvs\oss\icu\source\data\out\build\icudt35l" |
| Unicode .c source files built to "\cvs\oss\icu\source\data\out\tmp" |
| |
| - copy the .c source files to C:\cvs\oss\icu\source\common |
| and rebuild the common library |
| |
| *** Unicode version numbers |
| - makedata.mak |
| - uchar.h |
| - configure.in |
| |
| *** LayoutEngine script information |
| * Run ICU4J com.ibm.icu.dev.tool.layout.ScriptNameBuilder. This generates LEScripts.h, LELanguage.h, |
| ScriptAndLanguageTags.h and ScriptAndLanguageTags.cpp in the working directory. (it also generates |
| ScriptRunData.cpp, which is no longer needed.) |
| |
| The generated files have a current copyright date and "@draft" statement. |
| |
| * copy the above files into <icu>/source/layout, replacing the old files. |
| |
| Add new default entries to the indicClassTables array in <icu>/source/layout/IndicClassTables.cpp |
| and the complexTable array in <icu>/source/layoutex/ParagraphLayout.cpp. (This step should be automated...) |
| |
| * rebuild the layout and layoutex libraries. |

| |
| Unicode 4.1 update |
| |
| *** related Jitterbugs |
| |
| 4332 RFE: Update to Unicode 4.1 |
| 4157 RBBI, TR29 4.1 updates |
| |
| *** data files & enums & parser code |
| |
| * file preparation |
| - ucdstrip: |
| DerivedCoreProperties.txt |
| DerivedNormalizationProps.txt |
| NormalizationTest.txt |
| GraphemeBreakProperty.txt |
| SentenceBreakProperty.txt |
| WordBreakProperty.txt |
| - ucdstrip and ucdmerge: |
| EastAsianWidth.txt |
| LineBreak.txt |
| |
| * add new files to the repository |
| GraphemeBreakProperty.txt |
| SentenceBreakProperty.txt |
| WordBreakProperty.txt |
| |
| * update FractionalUCA.txt and UCARules.txt with new canonical closure |
| |
| * genpname |
| - handle new enumerated properties in sub read_uchar |
| - run preparse.pl |
| |
| * uchar.h & uscript.h & uprops.h & uprops.c & genprops |
| - new binary properties |
| + Pattern_Syntax |
| + Pattern_White_Space |
| - new enumerated properties |
| + Grapheme_Cluster_Break |
| + Sentence_Break |
| + Word_Break |
| - new block & script & line break values |
| |
| * gencase |
| - case-ignorable changes |
| see http://www.unicode.org/versions/Unicode4.1.0/#CaseMods |
| now: (D47a) Word_Break=MidLetter or Mn, Me, Cf, Lm, Sk |
| |
| *** Unicode version numbers |
| - makedata.mak |
| - uchar.h |
| - configure.in |
| |
| *** tests |
| - verify that u_charMirror() round-trips |
| - test all new properties and some new values of old properties |
| |
| *** other code |
| |
| * hardcoded Unihan range end/limit |
| - Unihan range end moves from 9FA5 to 9FBB |
| search for both 9FA5 (end) and 9FA6 (limit) (regex 9FA[56], case-insensitive) |
| + do not modify BOCU/BOCSU code because that would change the encoding |
| and break binary compatibility! |
| + similarly, do not change the GB 18030 range data (ucnvmbcs.c), |
| NamePrepProfile.txt |
| + ignore trietest.c: test data is arbitrary |
| + ignore tstnorm.cpp: test optimization, not important |
| + ignore collation: 9FA[56] only appears in comments; swapCJK() uses the whole block up to 9FFF |
| + do change line_th.txt and word_th.txt |
| by replacing hardcoded ranges with the new property values |
| + do change gennames.c |
| |
| source\data\brkitr\line_th.txt(229): \u33E0-\u33FE \u3400-\u4DB5 \u4E00-\u9FA5 \uA000-\uA48C \uA490-\uA4C6 |
| source\data\brkitr\word_th.txt(23): \u33E0-\u33FE \u3400-\u4DB5 \u4E00-\u9FA5 \uA000-\uA48C \uA490-\uA4C6 |
| source\tools\gennames\gennames.c(971): 0x4e00, 0x9fa5, |
| |
| * case mappings |
| - compare new special casing context conditions with previous ones |
| see http://www.unicode.org/versions/Unicode4.1.0/#CaseMods |
| |
| * genpname |
| - consider storing only the short name if it is the same as the long name |
| |
| *** other reviews |
| - UAX #29 changes (grapheme/word/sentence breaks) |
| - UAX #14 changes (line breaks) |
| - Pattern_Syntax & Pattern_White_Space |
| |

| |
| Unicode 4.0.1 update |
| |
| *** related Jitterbugs |
| |
| 3170 RFE: Update to Unicode 4.0.1 |
| 3171 Add new Unicode 4.0.1 properties |
| 3520 use Unicode 4.0.1 updates for break iteration |
| |

| |
| * file preparation |
| - ucdstrip: DerivedNormalizationProps.txt, NormalizationTest.txt, DerivedCoreProperties.txt |
| - ucdstrip and ucdmerge: EastAsianWidth.txt, LineBreak.txt |
| |
| * file fixes |
| - fix UnicodeData.txt general categories of Ethiopic digits Nd->No |
| according to PRI #26 |
| http://www.unicode.org/review/resolved-pri.html#pri26 |
| - undone again because no corrigendum in sight; |
| instead modified tests to not check consistency on this for Unicode 4.0.1 |
| |
| * ucdterms.txt |
| - update from http://www.unicode.org/copyright.html |
| formatted for plain text |
| |
| * uchar.h & uprops.h & uprops.c & genprops |
| - add UBLOCK_CYRILLIC_SUPPLEMENT because the block is renamed |
| - add U_LB_INSEPARABLE due to a spelling fix |
| + put short name comment only on line with new constant |
| for genpname perl script parser |
| - new binary properties |
| + STerm |
| + Variation_Selector |
| |
| * genpname |
| - fix genpname perl script so that it doesn't choke on more than 2 names per property value |
| - perl script: correctly calculate the maximum number of fields per row |
| |
| * uscript.h |
| - new script code Hrkt=Katakana_Or_Hiragana |
| |
| * gennorm.c track changes in DerivedNormalizationProps.txt |
| - "FNC" -> "FC_NFKC" |
| - single field "NFD_NO" -> two fields "NFD_QC; N" etc. |
| |
| * genprops/props2.c track changes in DerivedNumericValues.txt |
| - changed from 3 columns to 2, dropping the numeric type |
| + assume that the type is always numeric for Han characters, |
| and that only those are added in addition to what UnicodeData.txt lists |
| |
| *** Unicode version numbers |
| - makedata.mak |
| - uchar.h |
| - configure.in |

| - bidi tests: change exemplar character for ES depending on Unicode version |
| - change hardcoded expected property values where they change |
| |
| *** other code |
| |
| * name matching |
| - read UCD.html |
| |
| * scripts |
| - use new Hrkt=Katakana_Or_Hiragana |
| |
| * ZWJ & ZWNJ |
| - are now part of combining character sequences |
| - break iteration used to assume that LB classes did not overlap; now they do for ZWJ & ZWNJ |
