I recommend you ask Steven Loomis to sponsor this - and
probably the input method support, but particularly this one.

Hello

IBM would like to propose Unicode Variation Selector[1] capability to AWT
and Swing components.
(This proposal was posted to i18n-dev first, and I got a suggestion to discuss
 in 2d-dev.)

This proposal changed 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?
