third_party/icu38/README.google

 A. This directory contains the source code of ICU 3.8 for C/C++ with CJK
   segmentation, plural formatting and other locale-data updates added:
 
   - It was obtained with the following:
 
     1. Download the clean ICU source tree (revision 22777) with the following :
 
        $ svn export --native-eol LF -r 22777 http://source.icu-project.org/repos/icu/icu/trunk icu38
 
     2. Apply the following  patches :
         
        * segmentation.patch.txt  (CJ segmentation patch : code change + data)
        * data.patch.txt (ICU data customization patch)
        * data.patch2.txt, data.patch3.txt
          (Additional ICU data customization patches: to be applied on top of
           data.patch.txt)
        * eucjp.patch.txt (to be applied on top of 3 data patches above).
        * indian8_locales.txt (to be applied on top of above data paches) :
          Add locale data for 8 Indian languages
        * gbk.patch.txt (to be applied after the above patches) : Make
          GBK converter in ICU used outside Webkit behave identically
          to GBK converter used in Webkit (see
          WebCore/platform/text/TextCodecICU.cpp : getGbkEscapes())
        * windows.patch (Windows-specific patch)
        * uconv.patch (thread-safety patch for uconv. Ported from the ICU trunk)
        * wpo.patch (see section E).
        * plural.patch (for plural formatting. Ported back from ICU 4.0. See
          section G for details).
-       * uconv.security.patch (patches for ICU bug 5691/Chrome bug 2074.
-         The patch for HZ encoding is not included because we don't
-         support HZ).
+       * uconv.security.patch (files in source) and 
+         uconv.security.header.patch (header in public)
+         (patches for ICU bug 5691/Chrome bug 2074 and ICU bug 6071/Chrome bug 3823)
        * regex.patch (patch for ICU bug 6149/Chrome bug 8198)
 
   - Once CJK segmentation is included in an ICU release, we can use that
     release, instead of applying the first patch above.
 
   - The first patch contains the word frequency list derived from 3
     sources. For details, see the license terms and copyright notice
     at the beginning of the following two files:

   Besides, builds/icu.vcproj was modified to add plurrule.cpp and
   plurfmt.cpp to the list of files to compile. Note that this change
   is not a part of plural.patch because builds/icu.vcproj is 
   our own file.
