       a. Exemplar character set changes for zh*, ja + 9 Indian locales
       b. Minor fixes for Korean, a few Indic (AmPmMarkers) and 
       others (datetime format)
 
   - Locale build configuration files: To include the full locale data
     for Chrome's UI languages and the minimum locale data for other locales,
     add reslocal.mk or {trns,sprep,rbnf,coll}local.mk files to
     source/data/{coll,curr,lang.locale,curr,region,translit,zone,rbnf,sprep}.

+    This along with #8 (data.build.patch), #3 (brkiter) and #4 (converter) 
+    cuts down the data size by ~ 11MB.

+  - Run scripts/trim_data.sh : About 2.1MB data size reduction.
       a. Trim the locale data for Chrome's UI langauges :
          locales, lang, region, currency
       b. Trim the locale data for non-UI languages to the bare minimum :
         ExemplarCharacters, LocaleScript, layout, and the name of the
         language for a locale in its native language.
       c. Remove the legacy Chinese character set-based collation 
          (big5han/gb2312han) that don't make any sense and nobdoy uses.
