I have tried various workarounds to no avail, so here are test 
programs in java and jython.  The java works fine; the jython posts 
garbage.

When I tested them (I couldn't see the font either with java
or jython, but fontforge showed it), I found that jython
works with:

u'\u0F06' (no encode('utf-16')

At least, is shows just one (empty square) glyph. In fact,
this string is already encoded, and encoding it again won't
help.

and, using python2.2 or jython2.2a1:
>>> print "".join([unichr(i) for i in
xrange(3840,3847)])+"".join([unichr(i) for i in
xrange(3880,3890)])
 ()*+,-./01

is working from command line, as I paste it here. This after
I installed this font in /usr/fonts/local.

Not sure why java/jython don't show the font, though.

This code works for me:

from javax.swing import JButton, JFrame
from java.awt import Font

f = JFrame('Font Test')
font = Font.createFont(Font.TRUETYPE_FONT, open("TibetanMachineUniAlphaVolt.ttf"))
f.contentPane.add(JButton(u'\u0F06'))
f.pack()
f.visible = True

So I'm calling this fixed.
