<i18n dev> Proposal: Unicode Variation Selector

[Toshio 5 Nakamura]

Hello
IBM would like to propose Unicode Variation Selector[1] capability to AWT
and Swing components.


This proposal is changing the following files:
src/java.desktop/share/classes/sun/font/CMap.java
src/java.desktop/share/classes/sun/font/CharToGlyphMapper.java
src/java.desktop/share/classes/sun/font/CompositeGlyphMapper.java
src/java.desktop/share/classes/sun/font/Font2D.java
src/java.desktop/share/classes/sun/font/FontRunIterator.java
src/java.desktop/share/classes/sun/font/FontUtilities.java
src/java.desktop/share/classes/sun/font/TrueTypeGlyphMapper.java
src/java.desktop/share/native/common/font/sunfontids.h
src/java.desktop/share/native/libfontmanager/hb-jdk-font.cc
src/java.desktop/share/native/libfontmanager/sunFont.c
src/java.desktop/share/classes/javax/swing/text/DefaultEditorKit.java
542 lines will be changed.


There are three parts.
1) Adding CMap format 14 support
2) Adding CharsToGlyphs functions support Variation Selector Sequences
3) Swing text component's DEL and BS key operations change


How would I go about obtaining a sponsor?
