+Unicode 8.0 update for ICU ??
+
+* UCA issue from 7.0
+
+- U+1DE9 COMBINING LATIN SMALL LETTER BETA
+  sorts with Greek Beta, should sort with Latin B?
+  + Ken says:
+    No, it was deliberate:
+
+    03B2;GREEK SMALL LETTER BETA;Ll;;;;0392;;0392
+    1D5D;MODIFIER LETTER SMALL BETA;Lm;<super> 03B2;;;;;
+    1DE9;COMBINING LATIN SMALL LETTER BETA;Mn;<sort> 03B2;;;;;
+    1D66;GREEK SUBSCRIPT SMALL LETTER BETA;Ll;<sub> 03B2;;;;;
+
+    Note the relationship to U+1D5D.
+
+    When the disunified *Latin* beta base letter shows up in Unicode 8.0:
+
+    U+A7B4 LATIN CAPITAL LETTER BETA
+    U+A7B5 LATIN SMALL LETTER BETA
+
+    we could re-evaluate what U+1DE9 equates to, for collation,
+    but currently there isn’t any Latin beta to serve that function
+    in Unicode 7.0.

+
+*** data files & enums & parser code
+
+* file preparation
+
+- download UCD & IDNA files
+- make sure that the Unicode data folder passed into preparseucd.py
+  includes a copy of the latest IdnaMappingTable.txt (can be in some subfolder)
+- only for manual diffs: remove version suffixes from the file names
+  ~/unidata/uni70/20140403$ ../../desuffixucd.py .
+  (see https://sites.google.com/site/unicodetools/inputdata)
+- only for manual diffs: extract Unihan.zip to "here" (.../ucd/Unihan/*.txt), delete Unihan.zip
+- ~/svn.icutools/trunk/src/unicode$ py/preparseucd.py ~/unidata/uni70/20140403 $ICU_SRC_DIR ~/svn.icutools/trunk/src
+- This writes files (especially ppucd.txt) to the ICU4C unidata and testdata subfolders.
+- Restore TODO diffs in source/data/unidata/UCARules.txt

+  and copy to $ICU_ROOT/src/source/data/unidata/
+
+* initial preparseucd.py changes
+- remove new Unicode scripts from the

+  -> fix expectedLong names in cucdapi.c/TestUScriptCodeAPI()
+      and in com.ibm.icu.dev.test.lang.TestUScript.java
+- NamesList.txt now has a heading with a non-ASCII character
+  + keep ppucd.txt in platform charset, rather than changing tool/test parsers
+  + escape non-ASCII characters in heading comments
+- gets Unicode copyright line from PropertyAliases.txt which is currently still at 2013

+- download UCA files (mostly allkeys.txt) from http://www.unicode.org/Public/UCA/<beta version>/
+- run desuffixucd.py (see https://sites.google.com/site/unicodetools/inputdata)
+- update the input files for Mark's UCA tools, in ~/svn.unitools/trunk/data/uca/7.0.0/
+- run Mark's UCA Main: https://sites.google.com/site/unicodetools/home#TOC-UCA
+- output files are in ~/svn.unitools/Generated/uca/7.0.0/
+- review data; compare files, use blankweights.sed or similar

+    cp CollationAuxiliary/UCA_Rules_SHORT.txt $ICU_SRC_DIR/source/data/unidata/UCARules.txt

+- refresh ICU4J collation data:
+  (subset of instructions above for properties data refresh, except copies all coll/*)
+    ICUDT=icudt54b
+    ~/svn.icu/uni70/dbg$ make ICU4J_ROOT=/tmp/icu4j icu4j-data-install

+- run all tests with the *_SHORT.txt or the full files (the full ones have comments, useful for debugging)
+- note on intltest: if collate/UCAConformanceTest fails, then
+  utility/MultithreadTest/TestCollators will fail as well;
+  fix the conformance test before looking into the multi-thread test
+- copy all output from Mark's UCA tool to unicode.org for review & staging by Ken & editors
+- copy most of ~/svn.unitools/Generated/uca/7.0.0/CollationAuxiliary/* to CLDR branch
+  ~/svn.unitools$ cp Generated/uca/7.0.0/CollationAuxiliary/* ~/svn.cldr/trunk/common/uca/

+
+*** LayoutEngine script information
+
+(For details see the Unicode 5.2 change log below.)
+
+* Run icu4j-tools: com.ibm.icu.dev.tool.layout.ScriptNameBuilder.
+  This generates LEScripts.h, LELanguages.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 "@stable" statement.
+  ICU 54: Fixed tools/misc/src/com/ibm/icu/dev/tool/layout/ScriptIDModuleWriter.java
+  for "born stable" Unicode API constants, and to stop parsing ICU version numbers
+  which may not contain dots any more.
+
+- diff current <icu>/source/layout files vs. generated ones
+    ~/svn.icu4j/trunk/src$ meld $ICU_SRC_DIR/source/layout tools/misc/src/com/ibm/icu/dev/tool/layout
+  review and manually merge desired changes;
+  fix gratuitous changes, incorrect @draft/@stable and missing aliases;
+  Unicode-derived script codes should be "born stable" like constants in uchar.h, uscript.h etc.
+- if you just copy the above files, then
+  fix mixed line endings, review the diffs as above and restore changes to API tags etc.;
+  manually re-add the "Indic script xyz v.2" tags in ScriptAndLanguageTags.h
+
+*** API additions
+- send notice to icu-design about new born-@stable API (enum constants etc.)
+
+*** merge the Unicode update branches back onto the trunk
+- do not merge the icudata.jar and testdata.jar,
+  instead rebuild them from merged & tested ICU4C
